Incorrect and/or insufficient maintenance may cause product failure resulting in property loss, damage or injury or death. Maintenance intervals are critical for normal use, extreme use may require shorter or additional maintenance intervals. Manual content does not imply, express or other any warranty, the owner should read the limited warranty terms included in this booklet. MDC does not cover damage due to unauthorised modifications, misuse, abuse, incorrect assembly, improper and irregular maintenance or accident or collision. Before using this product, you should be certain your tow vehicle is suitably rated and equipped to tow the product safely and legally. The trailer and vehicle pairing must we within the safe “Maximum Towing Capacity,” “Ball Weight Capacity” and “Gross Combination Mass” as stated by the vehicle manufacturer. This Travel Trailer is fitted with electric brakes and a “Breakaway System.” Requirements for breakaway systems can vary from state to state. It is mandatory to supply a maintenance charge to the breakaway battery source while driving. You MUST ensure this capability is fitted to your vehicle. The maintenance charge is supplied to the Travel Trailer via the Anderson plug on the drawbar.
BALL LOADING (DOWNWARD LOAD ON TOW HITCH) MUST NOT EXCEED 550LB OR THE MAXIMUM ALLOWABLE LOAD BY THE VEHICLE MANUFACTURER OR TOW BAR RATING, WHICH EVER IS THE LOWEST. Exceeding these limits may result in an accident causing serious injury or death and/or property damage.
It is important to load your Travel Trailer correctly to distribute weight evenly and achieve a suitable ball weight load andprevent loading in a manner that can cause a Travel Trailer to sway and/or roll excessively left and right. The industry optimum ball weight on a Travel Trailer is between 9 and 11% of the total Travel Trailer weight. MDC Travel Trailers fit into this category and 10% should be used as the starting point.

If you believe that your vehicle has a defect that could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying MDC Caravans and Campers INC. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or Market Direct Group. To contact NHTSA, you may either call the Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-8004249153), go to http://www.nhtsa.gov; or write to: Administrator, NHTSA, 400 Seventh Street. SE., Washington, DC 20590. You can also obtain other information about motor vehicle safety from http://www.nhtsa.gov. Call 1833-632-8721 to reach MDC Caravans and Campers INC.
Tow vehicle and Trailer Compatibility
Your tow vehicle manufacturer has applied a maximum towing capacity to the vehicle which is the Gross Trailer Weight (GTW) and a maximum Gross Combined Weight Rating (GCWR). These specifications MUST NOT be exceeded. It is your responsibility to know, understand and follow these specifications. Vehicle manufacturers may also specify or recommend “Weight Distribution Bars” when towing under certain conditions. You MUST ensure this is compatible with the vehicle and trailer combination.

DANGER ­ Exceeding manufacturer weight and combination limits can result in loss of control leading to death or serious injury. Your tow vehicle and hitch must be rated for the Gross Vehicle Weight of the trailer.

Terminology & Abbreviations Cont’d
Tongue Weight: The downward load exerted on the tow point of the vehicle by the trailer. Dry Weight: The total weight of the trailer with no cargo, water, or propane. GVW (Gross Vehicle Weight): The total mass of the trailer and cargo. GVWR (Gross Vehicle Weight rating) Maximum rated total mass of trailer and cargo. GCWR (Gross Combination Weight Rating): This is the total allowable combined mass of tow vehicle and trailer as determined by the tow vehicle manufacturer. Camber: Camber angle is the measure in degrees of the difference between the wheel’s vertical alignment perpendicular to the surface. If a wheel is perfectly perpendicular to the surface, its camber would be 0 degrees. Camber is described as negative when the top of the tire begins to tilt inward towards the chassis rail. Your MDC trailer should be 0-0.5 degrees negative camber. Toe In/out: Negative toe, or toe out, is the front of the wheel pointing away from the centreline of the vehicle. Positive toe, or toe in, is the front of the wheel pointing towards the centreline of the vehicle. Toe can be measured in linear units, at the front or rear of the tire, or as an angular deflection. In the case of MDC products, the “toe in” is measured in degrees or 64th’s of an inch at the front of the tire from the chassis rail. Your MDC trailer should have toe in set at 3/64″ to 5/64″ over the diameter of the tire.
Secondary Escape
The secondary escape in your trailer is marked as “EXIT” and has red release handles as shown in the photo below. This escape must be clear and unobstructed for emergency escape should the main entry/exit door becomes inaccessible.
To use this escape:
1. Retract blinds/screen. 2. Turn red handles to open. 3. Escape through open window hatch.

Achieving a Safe Towing Combination
Ensuring a camper or Travel Trailer is safe and easy to tow is generally an easy thing to achieve, this doesn’t mean it’s always the case and sometimes, a vehicle and trailer combination may need some tweaking to make it ideal. There are a number of aspects that need to be correct in order to maximise towing safety and handling. It is important to use this information in conjunction with the maximum weight limits applied by your tow vehicle’s manufacturer as well as ensuring you stay within the maximum specified ratings of your Travel Trailer or camper. These can be found in the vehicle’s owner manual. This summary will address the main aspects, these aspects include, but may not be limited to the items listed in the following diagram:

11 | P a g e

www.mdcusa.com I Ph: 833-632-8721 I P a g e | 11

Trailer Tire Pressures
Tire pressures have a large effect on the handling and performance of any vehicle, be it a towed vehicle or motorized. The tire pressure on your camper or Travel Trailer will indeed be a major contribution to how well it tows and resists instability. Due to how much a camper or Travel Trailer may vary in weight depending on the cargo (as much as 3,500lbs to 7,700lbs in the MDC range) it is important to have your tires at the pressure recommended by the trailer manufacturer, for the actual weight of the trailer when loaded. You should follow the tire pressure guide in this manual for on road/highway tire pressures.
Tow Vehicle Tire Pressures
Equally as important as trailer tire pressure is the tire pressures in your tow vehicle. The added weight of the trailer ball weight should be factored into calculating the tire pressures in the rear of the car. What should also be factored in is the effect the distance of the hitch from the axles plays in leverage. A load on the tow bar of 250kg may well have the effect of 300kg or more on the vehicles rear tires meaning additional pressure must be applied. This will limit sidewall flex and sideways movement of the rear of the vehicle, limiting unwanted movement that can cause instability in the trailer.
Ball (Coupling) Weight
The ratio of overall weight of the trailer to the weight exhibited on the tow ball or coupling is an extremely important aspect of making a trailer handle correctly when towed. Generally, the ball or tongue weight allowed by most vehicle manufacturers is 10% of the maximum towing capacity. Given this ratio, the caravan industry builds campers and Travel Trailers with this in mind. When loading your MDC Travel Trailer, you should have a target ball or coupling weight of 10% or slightly higher to ensure the weight balance is at an ideal starting point. This figure should not be a guess, you should weigh your Travel Trailer with its normal load when travelling and use a ball weight scale to achieve the desires ball weight. These are an inexpensive item that will help you get the weight balance right when you load up for your trip.
Load Placement
Where you place the items in your trailer will affect how it behaves. Loading too much weight in the extremities of the trailer can have a very bad effect. MDC owner manuals have a loading guide to assist in this area. By following the guide and ball weight recommendations you’ll achieve the best possible result. Use the load placement guide in this manual as a reference for packing your Travel Trailer.
Trailer Level
The height of your hitch in respect to the level of the trailer will change the handling while being towed. The best practice with your MDC trailer is when loaded and hitched to the vehicle, the drawbar is NO higher than level. Ideally you should look to have the drawbar slightly lower than level between 0 and 50mm. Higher than level or too low will have an adverse effect on how the trailer tows.

12 | P a g e

www.mdcusa.com I Ph: 833-632-8721 I P a g e | 12

Hitch Movement
Most modern tow bars have an adjustable screw fitted to the hitch receiver that can be used to stop the hitch insert from rattling. Unfortunately this is not a sure fire way to limit sideways movement that can affect how well your trailer tows. Hitch movement from side to side can cause sway and when combined with a tow vehicle that has a greater distance between the rear axle centre and the hitch point, this affect can cause serious sway issues. Combine this with poor tire pressures on the tow vehicle and you have a recipe for disaster. If there is excess play in the hitch and hitch receiver, you may need to place shims either side of the insert to limit the movement. Shims are commercially available such as the pack below.
Vehicle Squat
When the back of a vehicle squats due to cargo and/or ball weight of the trailer, the handling of the tow vehicle can be changed to its detriment. Vagueness in steering, poor toe, camber, and caster settings due to reduced front suspension load, reduced brake and tire grip are often the result. All this in turn can result in a poorly handling towing combination. The best way to rectify this is upgrading the tow vehicle suspension to be suitable for the weights being experienced. Some vehicle manufacturers recommend Weight Distribution Hitches (WDH), this will be outlined in the vehicle owner manual and should be considered. You should also consult with the trailer manufacturer if this is an appropriate fitment to the trailer. The WDH should NOT be used in off road operation as it will NOT meet the required articulation that will be experienced. To better setup your tow vehicle suspension, it’s best to consult a suspension expert experienced with towing requirements.

Maximum Weight Limits
The following is an outline of the ratings that will be specified by the manufacturer of your vehicle and the camper/Travel Trailer manufacturer. These MUST be followed in conjunction with previously mentioned criteria for safe handling. None of the maximum ratings may be exceeded.
GVWR (Gross Vehicle Weight Rating)
This limit is specified by the trailer manufacturer and must NOT be exceeded under any circumstances. The ATM is the full weight of the loaded trailer including ball (coupling) mass.
Vehicle GVW (Gross Vehicle Weight Rating)
This is the loaded weight including fuel, passengers, cargo, and ball (coupling) mass of the attached trailer on the tow vehicle.
Axle Load
This is the maximum load on an axle specified by the tow vehicle manufacturer. It is possible to have your vehicle and trailer within ATM, GVM and GCM load limits but above the axle load limit specified. Be sure that this is not exceeded.

14 | P a g e

www.mdcusa.com I Ph: 833-632-8721 I P a g e | 14

GCWR (Gross Combination Weight Rating)
GCM is the maximum combined load of the tow vehicle and trailer, as specified by the tow vehicle manufacturer. Never exceed this maximum weight limit.

Summary
The above will assist in tuning or trouble shooting handling problems with your towing combination but are not the sole influences. Other items for consideration are:

· Wheel alignment on both vehicle and trailer. · Wear and tear on:
– Suspension bushes – Shock absorbers – Springs – Tires · Tow vehicle tire size (Oversize tires) · Extended hitches · Distance between axle centre and hitch point · Tow vehicle accessories (Weight distribution) · Real life tow vehicle capability (Not all vehicles are created equal) The purpose of this information is to help you to do a self-assessment and achieve a sound towing combination. If you are not confident you can achieve this, you should consult an expert to assist.

Tire Safety Information
This section of the User Manual contains tire safety information as required by 49 CFR 575.6.
Steps for Determining Correct Load Limit ­ Trailer Trailers 10,000 Pounds GVWR or Less
1. Locate the statement “The weight of cargo should never exceed XXX kg or XXX lbs” on your vehicles placard. See figure 1-1
2. This figure equals the available amount of cargo and luggage load capacity.
Tire and Loading Information Placard ­ Figure 1-1

3. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity.
The trailer’s placard refers to the Tire Information Placard attached adjacent to or near the trailer’s VIN (Certification) label at the left front of the trailer.
Note: The following calculations in Sections 2.1.2 and 2.2 are not required by the government. For the purpose of completeness, NATM has included these statements.
Steps for Determining Load Limit ­ TOW VEHICLE
1. Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.,” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers who will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage capacity. For example, if the “XXX”
amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage capacity calculated in Step # 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult the tow vehicle’s manual to determine how this weight transfer reduces the available cargo and luggage capacity of your vehicle.

Tire Safety ­ Everything Rides on it
The National Traffic Safety Administration (NHTSA) has published a brochure (DOT HS 809 361) that discusses all aspects of Tire Safety, as required by CFR 575.6. This brochure is reproduced in part below. It can be obtained and downloaded from NHTSA, free of charge, from the following web site: http://www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/tires_index.html
Studies of tire safety show that maintaining proper tire pressure, observing tire and vehicle load limits (not carrying more weight in your vehicle than your tires or vehicle can safely handle), avoiding road hazards, and inspecting tires for cuts, slashes, and other irregularities are the most important things you can do to avoid tire failure, such as tread separation or blowout and flat tires. These actions, along with other care and maintenance activities, can also:
· Improve vehicle handling. · Help protect you and others from avoidable breakdowns and accidents. · Improve fuel economy. · Increase the life of your tires.
This booklet presents a comprehensive overview of tire safety, including information on the following topics:
· Basic tire maintenance · Uniform Tire Quality Grading System · Fundamental characteristics of tires · Tire safety tips.
Use this information to make tire safety a regular part of your vehicle maintenance routine. Recognize that the time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire failure.
Safety First ­ Basic Tire Maintenance
Properly maintained tires improve the steering, stopping, traction, and load- carrying capability of your vehicle. Underinflated tires and overloaded vehicles are a major cause of tire failure. Therefore, as mentioned above, to avoid flat tires and other types of tire failure, you should maintain proper tire pressure, observe tire and vehicle load limits, avoid road hazards, and regularly inspect your tires.
Finding Your Vehicles Recommended Tire Pressure and Load Limit
Tire information placards and vehicle certification labels contain information on tires and load limits. These labels indicate the vehicle manufacturer’s information including:
· Recommended tire size · Recommended tire inflation pressure · Vehicle capacity weight (VCW­the maximum occupant and cargo weight a vehicle is designed to
carry) · Front and rear gross axle weight ratings (GAWR­ the maximum weight the axle systems are designed
to carry). Both placards and certification labels are permanently attached to the trailer near the left front.
Understanding Tire Pressure and Load Limits
Tire inflation pressure is the level of air in the tire that provides it with load-carrying capacity and affects the overall performance of the vehicle. The tire inflation pressure is a number that indicates the amount of air pressure­ measured in pounds per square inch (psi)­a tire requires to be properly inflated. (You will also find this number on the vehicle information placard expressed in kilopascals (kPa), which is the metric measure used internationally.) Manufacturers of passenger vehicles and light trucks determine this number based on the vehicle’s design load limit, that is, the greatest amount of weight a vehicle can safely carry and the vehicle’s tire size. The proper tire pressure for your vehicle is referred to as the “recommended cold inflation pressure.” (As you will read below, it is difficult to obtain the recommended tire pressure if your tires are not cold.) Because tires are designed to be used on more than one type of vehicle, tire manufacturers list the “maximum permissible inflation pressure” on the tire sidewall. This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.

Checking Tire Pressure
It is important to check your vehicle’s tire pressure at least once a month for the following reasons:
· Most tires may naturally lose air over time. · Tires can lose air suddenly if you drive over a pothole or other object or if you strike the curb when
parking. · With radial tires, it is usually not possible to determine underinflation by visual inspection.
For convenience, purchase a tire pressure gauge to keep in your vehicle. Gauges can be purchased at tire dealerships, auto supply stores, and other retail outlets.
The recommended tire inflation pressure that vehicle manufacturers provide reflects the proper psi when a tire is cold. The term cold does not relate to the outside temperature. Rather, a cold tire is one that has not been driven on for at least three hours. When you drive, your tires get warmer, causing the air pressure within them to increase. Therefore, to get an accurate tire pressure reading, you must measure tire pressure when the tires are cold or compensate for the extra pressure in warm tires.
Steps for Maintaining Proper Tire Pressure
· Step 1: Locate the recommended tire pressure on the vehicle’s tire information placard, certification label, or in the owner’s manual.
· Step 2: Record the tire pressure of all tires. · Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on the
tire valve stem with the edge of your tire gauge until you get to the correct pressure. · Step 4: If the tire pressure is too low, note the difference between the measured tire pressure and the
correct tire pressure. These “missing” pounds of pressure are what you will need to add. · Step 5: At a service station, add the missing pounds of air pressure to each tire that is underinflated. · Step 6: Check all the tires to make sure they have the same air pressure (except in cases in which the
front and rear tires are supposed to have different amounts of pressure).
If you have been driving your vehicle and think that a tire is underinflated, fill it to the recommended cold inflation pressure indicated on your vehicle’s tire information placard or certification label. While your tire may still be slightly underinflated due to the extra pounds of pressure in the warm tire, it is safer to drive with air pressure that is slightly lower than the vehicle manufacturer’s recommended cold inflation pressure than to drive with a significantly underinflated tire. Since this is a temporary fix, don’t forget to recheck and adjust the tire’s pressure when you can obtain a cold reading.
Tire Size
To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires, or another size recommended by the manufacturer. Look at the tire information placard, the owner’s manual, or the sidewall of the tire you are replacing to find this information. If you have any doubt about the correct size to choose, consult with the tire dealer.
Tire Tread
The tire tread provides the gripping action and traction that prevent your vehicle from slipping or sliding, especially when the road is wet or icy. In general, tires are not safe and should be replaced when the tread is worn down to 1/16 of an inch. Tires have built-in treadwear indicators that let you know when it is time to replace your tires. These indicators are raised sections spaced intermittently in the bottom of the tread grooves. When they appear “even” with the outside of the tread, it is time to replace your tires. Another method for checking tread depth is to place a penny in the tread with Lincoln’s head upside down and facing you. If you can see the top of Lincoln’s head, you are ready for new tires.
Tire balance and wheel alignment
To avoid vibration or shaking of the vehicle when a tire rotates, the tire must be properly balanced. This balance is achieved by positioning weights on the wheel to counterbalance heavy spots on the wheel-and-tire assembly. A wheel alignment adjusts the angles of the wheels so that they are positioned correctly relative to the vehicle’s frame. This adjustment maximizes the life of your tires. These adjustments require special equipment and should be performed by a qualified technician.

Tire repair
The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire that surrounds the puncture hole. Punctures through the tread can be repaired if they are not too large, but punctures to the sidewall should not be repaired. Tires must be removed from the rim to be properly inspected before being plugged and patched.
Tire fundamentals
Federal law requires tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides a tire identification number for safety standard certification and in case of a recall.
Information on Passenger Vehicle Tires

P The “P” indicates the tire is for passenger vehicles.
Next number This three-digit number gives the width in millimetres of the tire from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire.
Next number This two-digit number, known as the aspect ratio, gives the tire’s ratio of height to width. Numbers of 70 or lower indicate a short sidewall for improved steering response and better overall handling on dry pavement.
R The “R” stands for radial. Radial ply construction of tires has been the industry standard for the past 20 years.
Next number This two-digit number is the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter.
Next number This two- or three-digit number is the tire’s load index. It is a measurement of how much weight each tire can support. You may find this information in your owner’s manual. If not, contact a local tire dealer. Note: You may not find this information on all tires because it is not required by law.

19 | P a g e

www.mdcusa.com I Ph: 833-632-8721 I P a g e | 19

M+S The “M+S” or “M/S” indicates that the tire has some mud and snow capability. Most radial tires have these markings; hence, they have some mud and snow capability.

U.S. DOT Tire Identification Number This begins with the letters “DOT” and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3197 mean the 31st week of 1997. The other numbers are marketing codes used at the manufacturer’s discretion. This information is used to contact consumers if a tire defect requires a recall.

Tire Ply Composition and Materials Used The number of plies indicates the number of layers of rubber-coated fabric in the tire. In general, the greater the number of plies, the more weight a tire can support. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others.

Maximum Load Rating This number indicates the maximum load in kilograms and pounds that can be carried by the tire.

Maximum Permissible Inflation Pressure This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.

Treadwear Number UTQGS Information
This number indicates the tire’s wear rate. The higher the treadwear number is, the longer it should take for the tread to wear down. For example, a tire graded 400 should last twice as long as a tire graded 200.

Traction Letter This letter indicates a tire’s ability to stop on wet pavement. A higher graded tire should allow you to stop your car on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as “AA”, “A”, “B”, and “C”.

Temperature Letter This letter indicates a tire’s resistance to heat. The temperature grade is for a tire that is inflated properly and not overloaded. Excessive speed, underinflation or excessive loading, either separately or in combination, can cause heat build-up and possible tire failure. From highest to lowest, a tire’s resistance to heat is graded as “A”, “B”, or “C”.

Propane Safety
Appliances in your trailer are fuelled with propane. Propane is heavier than air which will allow it to pool in some areas creating an explosion risk. It is mandatory to follow all manufacturer guidelines in the use of propane appliances.

· The propane system and appliances installed on the trailer are designed and installed to comply with all relevant statutes and laws.
· Modification or misuse may result in explosion resulting in death or serious injury. · Follow manufacturer guidelines at all times.
IF YOU SMELL PROPANE 1. Extinguish any open flames and all smoking materials. 2. Shut off propane supply at the container(s) or propane supply connection. 3. DO NOT touch electrical switches. 4. Open doors and other ventilating openings. 5. Leave the area until odor clears. 6. Have the propane system checked and leakage source corrected before using again.
Ignition of flammable vapors could lead to a fire or explosion resulting in death or serious injury.

Gas Certification
Your Travel Trailer has been supplied gas tested and certified. Any additions or alterations to the gas system must be performed by an authorized person and will require re-certification and testing. Also note any alterations may affect your warranty on both the system and appliances.
General Safety

·

Your Travel Trailer may have a number of gas safety labels affixed throughout containing

important information. Allinstructions are to be followed and the labels shall not be removed for any

reason.

· Make sure to close appliance valves before opening the cylinder valves.

· Where readily accessible, check connections at the appliances, regulator, hoses, and cylinders periodically forleaks with soapy water (or an equivalent) ­ this should be done every time a cylinder is changed or at least annually.

­ the ammonia present in some soaps and detergents can react with brass fittings and cause such fittings to crack after a short period of time. Therefore, caution should be exercised when using soap solutions on brass fittings and all connections should be rinsed thoroughly with fresh water as soon as possible after the application of the soap solution.

·

NEVER use a match or flame when checking leaks.

·

NEVER use cooking appliances for comfort heating. This can lead to carbon

monoxide poisoning that can lead to death or serious injury.

· In the event of a fire, immediately close cylinder valve if safe to do so.

· Appliances must not be altered without the authorization of the manufacturer.

· In the event of an accidental gas leak, close cylinder valve and ventilate the area using a safe method

until the air is clear.

· Flexible hoses are used between the Propane Gas Cylinder and regulator as well as between your

slide-out kitchen cooker (if fitted) and the gas bayonet. These flexible hoses are easily accessible and

shall be inspected regularly by a competent person.

Propane Cylinder Safety

DO NOT place propane cylinders inside the vehicle.
Propane cylinders are equipped with safety devices that relieve excessive pressure by discharging propane to the atmosphere. Propane gas is highly flammable and can lead to a fire or explosion and result in death or serious injury.

·

Propane Gas cylinders have a 12-year lifespan between inspection and re- certification. Always

use gas cylinders that are within their compliance date.

·

For drawbar mounted cylinders (if applicable), orient the cylinder relief valves of both

cylinders discharge away from both the trailer and towing vehicle as shown.

· Always remove the propane cylinder from the trailer to refill.

·

Propane tanks may only be filled to 80% capacity. DO NOT OVER FILL. A properly

filled propane tank contains approximately 80% of its volume as liquid propane. Overfilling a propane

container can result in uncontrolled propane flow, which could lead to a fire or explosion resulting in death or serious injury.

· For gas cylinders stored in a dedicated Propane Gas Locker ensure the locker is kept closed at all

times unless changing or operating the cylinders.

· Close cylinder valves when appliances are not in use or while refuelling is in progress.

· Ensure cylinder valves are closed to prevent the unintended release of gas from a cylinder.

Gas Appliance Safety
DO NOT use gas cooking appliances for comfort heating. This can lead to carbon monoxide poisoning, which can lead to death or serious injury.
Gas cooking appliances need fresh air for safe operation. Before operation: Open vents or windows slightly or turn on exhaust fan prior to using cooking appliance. Gas flames consume oxygen, which should be replaced to ensure proper combustion. Improper use can result in death or serious injury.
· Gas appliances are certified and have a flame safeguard feature to stop gas flow in the event of the flame goingout. Never interfere with this function or replace appliances with a non-certified type.
· Slide-out kitchens with cookers should only be operated with an annex fully erected. Failing to do so may affect the safety and operation of the gas appliance.
· Slide-out kitchens with cookers must only be used with a flexible connecting hose that is disconnected from the gas bayonet fitting when in its stored position. Under no circumstances permanently connect this appliance.
· Only approved and suitable gas appliances with flame safeguard systems shall be connected to the gas bayonet(if fitted).
Removing Door Vent Cover
The door vent must be uncovered at any time the Travel Trailer is occupied.
Isolating Appliances
Internal gas appliances have an isolation valve fitted to the gas line. During travel these should be turned to the off position where practical and always turn the valve on the active gas bottle off when towing.

Brake Controller
Your trailer is fitted with drum type electric brakes. The tow vehicle MUST be fitted with an appropriate brake controller for the trailer brakes to activate and brake. The company will not hand over a trailer to be towed by a vehicle without a suitable controller installed. Your trailer brakes are designed to work in synchronization with your tow vehicle brakes. Never use your tow vehicle or trailer brakes alone to stop the combined load. Your trailer and tow vehicle will seldom have the correct amperage flow to the brake magnets to give you comfortable, safe braking unless you make proper brake system adjustments. Changing trailer load and driving conditions, as well as uneven alternator and battery output, can mean unstable current flow to your brake magnets. It is therefore imperative that you maintain and adjust your brakes as set forth in the controller manual, use a properly modulated brake controller and perform the synchronization/adjustment procedure recommended by the brake controller supplier.

Jacking Your Trailer
Your trailer is fitted with purpose built jacking points and from January 2021 supplied with a suitable jack. An appropriately rated bottle jack is an acceptable alternative, however when using the jacking point beneath the trailing arm ensure the jack is of a retracted height that will fit under the jacking point when the tire is deflated. A suitably rated “High Lift” jack may be used on the jacking points on the side of the body behind the wheels provided it has the correct positive engagement fitting to match the trailer. To ensure safe usage the following must be followed:

· The jack is to be used on level firm ground wherever possible.

· The wheels of the trailer should be chocked, and no person should remain inside the trailer whilst it is

being jacked.

· No person should place any portion of their body under a trailer that is supported by a jack.

· The trailer should be attached to the towing vehicle whilst being jacked.

· When performing maintenance ensure suitably rated jack stands are used ­ do not rely on the trailer

being supported by the jack.

Using Your Trailer

Instructions below are for your safety and the avoidance of accidental damage to the trailer through misuse. Follow all directions given in this manual and the manuals for third party products installed.
The manufacturer has produced product specific video content for tutorial purposes, to assist in the correct setup and use. It is important to view and understand the instructions to avoid accidental damage to the product to prevent damage.
Connecting to the Tow Vehicle

WARNING ­ Your coupler MUST be rated for the Gross Vehicle Weight and be in serviceable condition.

·

The hitch MUST be correctly load rated.

·

Hitch and pin MUST be compatible.

All bolts and fittings must be correctly tightened and serviceable condition.

Towing with Trucks and Buses
If you intend to tow your trailer with a truck or heavy commercial vehicle you should fit a hitch system to minimize the lash effect of the commercial suspension and distance from the rear axle to the tow point. Truck suspension can be harsh, particularly in off road conditions. The long distance between the axle centre and the point of attachment can be quite long, further exacerbating the effect putting stress on components. Using a shock absorbing hitch will reduce the effect considerably.

Connecting the Breakaway
The breakaway lanyard is connected to a simple switch on the drawbar. When connecting the lanyard to the tow vehicle it should be connected to a solid part of the vehicle. Do not incorporate its connection with the safety chains.

Breakaway Switch

Lanyard Connection

WARNING ­ Where fitted, the breakaway system lanyard must be connected to a secure part of the tow vehicle.
· Do not connect to the safety chain shackle. Connect only to a fixed structural part of the tow vehicle. · Ensure the battery system has adequate charge to power the electric breakaway system in the event
of the trailer separating from the tow vehicle. · The tow vehicle should supply a maintenance charge to the trailer batteries while towing to ensure
peak battery capacity for the breakaway system.
Operating the Jockey Wheel
The rated load capacity of a jockey wheel is achieved when the jockey wheel is retracted to its lowest position.
When moving the trailer on the jockey wheel, always lower it as far as possible but still allowing the wheel to swivel as you steer the trailer.

Loading Your Trailer
Loading your trailer can have an effect on the overall handling of the trailer and tow vehicle combination. Loading affects tongue weight and balance which must be taken into consideration.
· DO NOT exceed the Gross Vehicle Weight Rating (GVWR) or the stated cargo capacity which can be found on the trailers tire placard or load carrying capacity label.
· Always load cargo and luggage to keep weight even on both sides of the trailer. · Always load to achieve around 10% of total load as Tongue weight. This is a generally recommended
standard to achieve a safe balance for handling.

Pre-Trip Inspection
Before any trip check the following
Tires
· Correct tire pressures · Tires are in good condition free from damage and uneven wear. · Tread is of legal and acceptable depth.
Wheel Nuts
· Ensure wheel nuts are tensioned to the correct torque using a torque wrench. · All wheel nuts are in place. Hitch and Chains
· Ensure hitch and chains are free of damage. · Hitch locking mechanism functions correctly. · Hitch is properly lubricated. · Hitch articulates correctly. Fire Extinguisher
· Extinguisher is properly mounted and within date. · Extinguisher charge gauge is in green. Brakes & Breakaway System
· Brakes operate correctly when both operated by manual control and via pedal. Lights
· Ensure all trailer lights are functioning.

Operating Trailer Features
This section covers details on using the common features on your trailer correctly.
Stabilizer Legs
The Stabilizer legs are fitted to make the trailer stable when occupied. Important things to note are: · Always try to set the Stabilizers up in a vertical position, 90 degrees to the chassis as shown in figure below. · Do not try and lift the full trailer weight when winding out the Stabilizer. There are small bevel gears and roll pins that may shear when overloaded. · When setting down or stowing Stabilizer legs, ensure the pins on the release handle correctly engage to stop the leg collapsing under load or lowering during transit. · Disassemble and maintain according to the maintenance schedule.
Connecting Shore Power
You can connect your trailer to shore power via the external input socket pictured below. Always ensure the following: · Only use this connection for 110-120 volt AC, 60 hz 50 ampere supply. · Do not exceed circuit rating. · Site power is protected with an RCD device. · Power leads are not coiled but laid out alongside the trailer without causing a trip hazard.

Setting up your Travel Trailer
Finding a Suitable Spot
When choosing a spot to set up your Travel Trailer, start with a flat area with no overhanging trees. Birds and bats occupying trees can defecate leaving droppings on your Travel Trailer that can damage paint and leaves and sap can also stain the coating. Ensure you are not camping in an area prone to flooding or with bad drainage in the event of rain. Even the slightest hollow in the ground can put you in a mini lake. In hot weather, if possible, set your Travel Trailer up so the sun’s arc goes from front to back or back to front with the annex/awning in the general direction the sun is arcing across. Doing this will keep the bulk of the Travel Trailer in shade and the inside cooler as it will be shaded by the awning.
Weather
It is important to know the weather prediction for the area you are camped. Storms can be destructive with items such as awnings and annexes being particularly vulnerable to wind and storm damage.

Towing Your Trailer
Driving dynamics change considerably when towing a trailer. Many facets of driving need to be modified when towing for your safety and that of other road users.
Important points you must know, understand, and adhere to are:
· Do not exceed the manufacturer maximum capacities for the tow vehicle or trailer. · Do not exceed the manufacturer capacity on hitch (770lbs for Cruisemaster DO35) · Do not exceed the maximum Tongue weight allowance of the tow vehicle or trailer (whichever is lowest)
Speed and Road Conditions
· Never exceed the recommended or allowed towing speed in the state you’re travelling. Recommended and maximum speeds may vary from state to state.
· Greater speed can lead to instability when towing. Always tow at a safe speed for the conditions you’re driving.
· When towing, always allow greater safe distance for braking. · Windy conditions and wind buffeting from other vehicles may affect the behavior of your vehicle and
trailer possibly causing sway. Always keep this in consideration and modify your driving accordingly. · Testing road and environments may cause fatigue. Ensure adequate rest and regular breaks when towing.
WARNING ­ Excessive speed, sudden steering input, bad road conditions and fatigue may lead to a loss of control causing death or serious injury. Ensure driving behavior is modified to suit conditions and take regular breaks.
Trailer Sway
Incorrect loading, incorrect tire pressures and setup can affect how a trailer responds when towed. If you encounter trailer sway, you should do the following.
· Reduce speed using only the trailer brakes via the manual control on your brake controller. · Find a safe place to pull over. · Check hitch connection. · Check tire pressures. · Check wheel nuts · Move heavier cargo towards the front of the trailer. Once checked and rectified proceed with caution while testing the outcome.
Fatigue
Towing a trailer can be tiring and regular breaks should be taken. Overlanding with a trailer can be even more tiring and requires more frequent breaks when driving off road. When taking regular breaks, use the opportunity to check your vehicle and trailer hitch and take general look over the trailer, to ensure everything is as per normal.
Daily Checks
On extended travel over a period of days or longer, some regular checks should be done to ensure reliable and safe towing. The below list identifies common items that should be done each day before travelling.
· Check wheel nut torque using a torque wrench to correct torque setting. · Check hitch connection and operation. · Inspect tires for damage and inflation.

Care and Maintenance of the Trailer
Protection of Finishes
Paint The paint coatings on your trailer are no different to that of your car in that they need regular care and maintenance. Rubber seals and applied sealants on trailers can shed polymers and pigments that can stain paint finishes if your trailer isn’t washed regularly.
Washing: Only use mild detergents free of ammonia when washing your trailer. Always check the label to ensure the washing solution is nonabrasive, contains no ammonia or caustics.
Polishing: New trailers should only be polished with wax-based polishes that are nonabrasive. When removing scratches from paintwork use a fine finishing compound. Cutting pastes are too abrasive and will expose the base material.
Protection: Carnauba wax is an excellent protection against oxidizing. The paint on your trailer should be waxed annually regardless of being kept under cover to protect the surfaces from oxidisation.
Acrylic Windows Windows should be cleaned with a clean, soft, nonabrasive cloth to avoid scratches and soapy water. Do not use any cleaners that contain ammonia or solvents.
Internal Finishes Laminates and internal wall surfaces should be cleaned with a damp soft cloth. For stubborn marks use a mild detergent based cleaner. Do not use cleaners that contain ammonia or caustics
Ensuite Finishes Never use harsh detergents or bleach based products on the toilet or sealants in the ensuite. Use of such products will damage the seals and sealants.
Mirrors Do not use solvents or chemicals when cleaning mirrors. Warm water and a soft, clean cloth are the best method. Cleaners and solvents may affect the reflective backing causing what’s known as “creep” where the edges of the mirror discolor.
Galvanized Finishes Your galvanized chassis will need maintenance when used off road. The zinc coating. although being tough. is still susceptible to damage from stone chips. the coating should be maintained.
High Tensile Bolt and Fittings Zinc plated bolts and fittings should be coated with a protectant such as a lanolin based spray. The proprietary item “Lanotec” is recommended.
Stainless Steel Do not use abrasive cleaners on stainless steel. Purpose made stainless steel cleaners are recommended as are solutions such as 10% white vinegar in water.
Fabrics Fabrics may not be colorfast and should be washed gently by hand on their own or dry cleaned.
Corrosion Protection Reasonable steps should be made by the customer to protect the product from corrosion. Seaside areas, areas with high salt contents in soil and roads that are salted during snow conditions can greatly accelerate corrosion. When used in these areas the product should be thoroughly washed after use and unpainted metal surfaces should be coated in a suitable protectant. Lanotec lanolin spray, Inox or similar are recommended.

Solar Panels
Accumulated dirt and soiling can affect the performance of the solar panels. Panels should be cleaned as necessary to prevent this. Sealants around solar panel mounts should be checked annually to ensure they are in good condition.
Sealants
Roof sealants should be inspected every 6 months for condition. If the sealant has perished or adhesion has failed, it should be repaired immediately.
Trailer Body Maintenance
Locks and Latches
Locks need regular maintenance to ensure they operate correctly and stay free from corrosion. Diligent use of WD40 or Inox will help in this regard. Both locks and latches need to be checked for adjustment to ensure correct seal compression.
Rubber Seals
Rubber seals are critical in reducing or eliminating dust and water ingress. Damaged or worn seals should be replaced immediately. Seals that are overly compressed will stay flattened and be less effective. (See maintenance
Winterizing the Trailer
Winterising your trailer is an important part of storage during the winter months to avoid damage to water lines, pumps, and appliances such as hot water systems.
For appliances such as hot water systems, consult the product user manual for winterizing the appliance.
To winterize your trailer, follow the steps outlined below.
Water Heater Bypass Installed
1. Activate water heater bypass. 2. Follow steps in water heater user manual for draining unit. 3.

Mechanical Maintenance
WARNING ­ Failing to maintain your trailer adequately COULD result in severe personal injury or death if the warning is ignored. Maintain according to the maintenance schedule as a minimum requirement.
Wheels and Tires
Tires should be checked for damage prior to each trip. Inspect for adequate tread depth and any damage particularly to sidewalls. Wheel nuts must be checked with a torque wrench. When picking up your new trailer. check the wheel nut torque at 25, 50, 100 and 300 miles. Check before each trip and daily when travelling for longer periods. Do not over tighten, always use a torque wrench to ensure accuracy.
Brakes
The electric brakes on your trailer are a drum type. Drum brakes require regular adjustment to ensure even pad wear and proper performance. This is an important safety item. The recommended maximum interval for checking adjustment is 3000 miles.
Brake Adjustment
Brakes should be adjusted (1) after the first 150 miles of operation when the brake shoes and drums have “seated,” (2) at 3000 mile intervals, (3) or as use and performance requires.
Never crawl under your trailer unless it is resting on properly placed jack stands. Do not place supports on any part of the suspension system and use the designated jack point or under the spring base plate to jack trailer.
Brake Cleaning and Inspection
Your trailer brakes must be inspected and serviced at 3000 miles or more often as required by use and performance. Magnets and shoes must be changed when they become worn or scored to avoid inefficient vehicle braking.
Brake Lubrication This should only be done by qualified persons.
Do not get grease or oil on the brake linings, drums, or magnets.

47 | P a g e

www.mdcusa.com I Ph: 833-632-8721 I P a g e | 47

Magnets
Your electric brakes are equipped with high quality electromagnets that are designed to provide the proper input force and friction characteristics. Your magnets should be inspected and replaced if worn unevenly or abnormally.

Even if wear is normal as indicated by your straightedge, the magnets should be replaced if any part of the magnet coil has become visible through the friction material facing of the magnet. It is also recommended that the drum armature surface be refaced when replacing magnets.
Magnets should also be replaced in pairs – both sides of the axle. Always use genuine MDC OEM parts.
Shoes and Linings
A simple visual inspection of your brake linings will tell if they are useable.
Replacement is necessary if the lining is worn (to within 1/16″ or less), contaminated with grease or oil or abnormally scored or gouged. It is important to replace both shoes on each brake and both brakes of the same axle. This is necessary to retain the “balance” of your brakes. Be sure to replace your shoes only with genuine MDC parts available from our outlets.
Important Safety Notice
Proven and in some cases approved service methods and correct repair procedures are essential for the safe, reliable operation of the brakes, suspension, and axles as well as the personal safety of the individual doing the work. This manual intends to provide general directions for performing service and repair work with tested, effective techniques. By following these guidelines, it will help assure reliability. The numerous variations in procedures, techniques, tools, and parts for servicing axles, as well as in the skill of the individual doing the work will determine outcomes.

the appliance works
The appliance was developed exclusively for use in recreational vehicles (RVs).

How

The appliance is connected between the vehicle’s fresh water supply and its hot water plumbing system.

It is powered by propane and a 12 V power supply. The ventilation grille on the access door allows combustion air to flow into the appliance and exhaust gas to flow out.

When the appliance is switched on, the water will be heated on demand:

· A volume-flow sensor in the appliance detects when the hot water faucet has been opened and the volume flow is greater than approximately 0.4 gallons/min (1.5 liter/min). The burner then starts automatically.
· The burner control continuously adjusts the heater output based on volume flow and inlet water temperature, so that the temperature at the hot water outlet is approximately 120 °F (49 °C). A temperature stabilizer is also installed in the appliance to minimize fluctuations of the outlet temperature.
· After some time the maximum temperature at the faucet or in the shower is reached. The length of time will depend on the model (AquaGo basic, AquaGo comfort and AquaGo comfort plus) and variations in the water plumbing (length of pipes, insulation, circulation line, etc.). Like in a home shower, a comfortable water temperature at the shower head is reached by mixing in cold water.
· When the volume flow is less than approximately 0.4 gallons/min (1.5 liter/min) and the faucet is closed, the burner is automatically switched off.
The AquaGo comfort and AquaGo comfort plus models are equipped with a circulation pump. The circulation pump as well as the burner are switched on automatically by the control unit in order to keep the water temperature above 102 °F (39 °C) in “COMFORT” mode and 41 °F (5 °C) in “ECO” mode.

Risk of damage in frost conditions. Refer to “Operation in frost conditions”.

Description
There is a flame-detection error at the burner because the flame was not detected after release of gas and ignition. Important: The system indicates this error only after three attempts at intervals of approximately 30 seconds. The exhaust over temperature switch (EOS) or burner over temperature switch (BOS) is open/unplugged. The EPS did not close when the flue fan was actuated because the fan did not push enough air through the exhaust channel. A cause could be, e.g., blocking of the exhaust channel or a faulty switch. OR The EPS is closed even though the flue fan is not running. Cause is a defective EPS or flue fan. The WOS opened at a water temperature of over 185 °F (85 °C).
There is an error in flame detection of the burner because the flame was detected ­ before ignition or ­ before the release of gas or ­ after the gas was switched off. There is a heating request, but gas cannot be released. One of the switches WOS, EOS, BOS, EPS is open/unplugged.
