DECKED DT1 Toyota Tundra 5’7 Inch Bed Length Decked Truck Bed
Storage System

READ BEFORE YOU INSTALL DECKED

DON’T use power tools to assemble or install the DECKED system. Impact wrenches and other power tools can over-tighten and damage components (aside from drilling drain holes in ammo cans).
DON’T over-tighten J-hooks during installation. J-hooks need to be snug to keep the system from moving around, but should NOT be cranked down.
DON’T over-torque any bolts, particularly the bolts attaching the center vert to the deck halves. TAILGATE ammo cans have flat bottoms; CAB SIDE ammo cans are narrow at the bottom.
NOTE: You will need a buddy with exactly two steps.

AMMO CAN DRAIN HOLES TO DRILL OR NOT TO DRILL

Do you use a Tonneau or shell over your DECKED system?
There is no need to drill holes.
Does your DECKED system live outside in the elements?
The ammo cans will likely get water in them. You’ll need to drill holes in the ammo cans. There are two dimples in the bottom of each ammo can. Drill a 3/8” hole at each dimple.

PREPARE BED INSTALL SHIMS

There are 4 SHIMS provided:
Using the information in the respective circular detail views:
a) Clean the surfaces thoroughly where the shims will be located (isopropyl alcohol is recommended).
b) Remove the layer of tape on the bottom of the shim to expose the adhesive surface.
c) Place the shim and apply with pressure.

NOTE: DETAIL A and B are to be repeated on the passenger side.

DETAIL A
Place shim 5.5” from the tailgate side of the floor. Center shim between floor beads shown. Repeat opposite side.
DETAIL B
Place shim 3” from the cab side panel. Center shim between floor beads shown. Repeat opposite side.
