The vertically adjustable bed is movable between elevated and lowered positions by hydraulic cylinders. When in its fully elevated position, the vertically adjustable bed is secured to the U-shaped frame by bed locking pins. When the vertically adjustable bed is in its fully elevated position, left and right tailgate doors are secured to each other by tailgate door locking screws. The left and right tailgate doors are secured to the vertically adjustable bed by tailgate bed locking pins and a lateral recess in the left and right tailgate doors designed to receive the rear edge of the vertically adjustable bed.
