Abstract: An adjustable enclosure for a vehicle is disclosed where the roof and rear portions of the enclosure can be moved to expose portions of the vehicle previously enclosed. The adjustable enclosure includes roof panels that can slide and collapse on top of each other to be conveniently stored above another part or inside of the vehicle. A truck bed can be enclosed with the current invention where the roof panels can be stored above the cab of a truck. The adjustable enclosure can also be used on a sport utility vehicle where the rear portion of the roof can collapse over the front portion. This adjustable enclosure enables the same vehicle to be used as both a fully enclosed vehicle, capable of comfortably transporting passengers or other items, and a partially open vehicle, capable of transporting oversized items or otherwise exposing the rear portion of the vehicle.
