Abstract: An improved camper shell adapted to be mounted to the bed of a pickup truck or similar vehicle is disclosed. The camper shell includes a shell structure having an appearance similar to a standard camper shell when the vehicle is in motion. However, a major portion of the roof is hingeably mounted to the trailing end of the forward portion of the roof along an axis normal to the direction of travel of the vehicle. The movable portion of the roof can thus be raised at its trailing end when the vehicle is parked, and flexible sheet material encloses the space provided by the raised roof. A ceiling structure spans the side portions of the shell structure immediately beneath the movable portion of the roof in its lowered configuration. A bunk is mounted to the upper surface of the ceiling structure to provide an extra sleeping area when the movable portion of the roof is raised.
