A collapsible cap assembly for a pickup truck or the like includes a pair of track members mounted to the side walls of the pickup truck box, and a series of frame members mounted to the track members. A front frame assembly is stationarily mounted to the track members, and a rear frame assembly and a pair of intermediate frame members are movably mounted to the track members for movement between an extended operative position and a collapsed storage position. A handle is pivotably mounted to the rear frame assembly for assisting in movement of the rear frame assembly and the intermediate frame members between their operative and collapsed positions. A window and door assembly is mounted to the rear frame assembly. The window and door assembly can either be pivoted upwardly and outwardly to provide access to the interior of the cap when in its extended operative position, or pivoted upwardly and inwardly when the cap assembly is moved to its storage condition for providing unobstructed use of the forward portion of the pickup truck box when the cap assembly is collapsed. The invention further includes a simple and unique track system for providing movement of the rear frame assembly and the intermediate frame members between their operative and storage positions, and a removable support rod system for supporting the cover of the cap assembly between the frame members.
