Abstract: A rack is disclosed which is adapted to be installed in combination with a shell in the bed of a pickup truck. The rack comprises two opposed sets of upright posts. Each set of posts is adapted to extend in a plane generally parallel to the sidewall of the truck and outside of the sidewall. The upper portion of the rack is completed by a pair of horizontal side members extending along the top of the posts and a plurality of horizontal cross members extending between the side members. Each set of posts is supported by a base plate which is disposed horizontally along the bottom of the posts and extends inwardly from the plane of the posts to the sidewall of the truck bed. The inward portion of the base plate is fastened to the top of one of the sidewalls. The rack provides a clearance so that a shell may be mounted over the truck bed within the rack, and the rack is supported entirely by the sidewalls of the truck bed.
