Abstract: Two panel assemblies are separately mounted on the side walls of a pickup truck by means of integral legs which fit into stake pockets provided by the truck. When these panel assemblies are so mounted, cross bars join the top portions of opposing panel assemblies to provide additional vertical stability to the panel assemblies and to serve as a top carrier. When removed from the side walls and longitudinally joined together in a single plane, these panel assemblies are hooked into the rear of the bed of the truck and extend from the rear of the truck to provide a loading ramp to the bed of the truck.
