TRUCK BED INSTALLATION GUIDELINES
CAUTION:
Please read carefully. The following guidelines cover important points for
safe and proper installation of standard configuration Truck Beds.
Before installing the truck bed:
•
Make certain that the width of the truck bed frame rails and the width of your
truck frame rails are compatible. If they are not, please call Trinity Trailer Mfg.,
Inc. at 1-800-235-6577 for installation assistance.
•
Place the provided 3”x 3/8” rubber strip (cut to the length of the truck bed frame)
to the top of the truck frame (on both sides). Once the mounting is complete
these rubber strips will help stabilize and cushion the truck bed on the truck
frame rails.
•
Place the truck bed on the truck chassis, such that, the front cover is 1 inch
behind the rear of the truck cab or most rearward truck cab protrusion. The rear of
the truck frame should allow the truck bed to lay flat on top of the frame rails
with no interference with the tail section.
•
Make certain the Truck Bed ribs clear all tires (including lift axle tires).
•
DO NOT WELD MOUNTING BRACKETS TO TRUCK FRAME
