ABSTRACT:
A trailer has a torque arm assembly pivotally mounted between the upper front portions of a pair of opposed side walls. A bottom is slideably and pivotally supported upon a bottom support member extending between the side walls and has a upwardly extending front wall the upper edge of which is pivotally connected to a pair of torque arms extending from the torque arm assembly. Also extending from the torque arm assembly is a mounting post which can be pivotally and rotatably connected to a mounting rack detachably fastened to the bed of a pick-up truck. The torque arm assembly is pivotable between one position in which the bottom is horizontal and a second position in which the bottom is inclined downwardly toward the rear end of the frame. In the second position, the mounting post is pivoted inwardly with respect to the trailer so that the truck is received in a retracted position between the side walls of the trailer.
