A camping conversion for motor vehicles having an open interior compartment. The conversion includes a floor panel supported by tracks and retractable beneath the vehicle floor, and an auxiliary pop-out compartment which protrudes from the side of the vehicle and is retractable into the vehicle interior. In the extended position, the auxiliary pop-out compartment rests on the extended floor panel. The auxiliary pop-out compartment has telescoping sidwalls which overlap one another when retracted to save interior space.
