Abstract
Abstract A trailer is disclosed having a verticaly positionable roof to permit towing with minimum drag and buffeting. Electromechanical actuators position the roof. A rear wall is comprised of ramps which abut one another and brace the rear upright edges of the trailer sidewalls. A side door of the trailer permits entry and exit from an automobile parked in the trailer. A skirt portion of the roof additionally includes a door overlying the first-mentioned door to permit standard door height. Collapsible shelves within the trailer facilitate secondary use of the trailer when parked. The trailer ramps are spring biased to facilitate their positioning.
