Abstract: A track-mounted trunk-type luggage-carrier body is longitudinally movable from its transporting position on the top of a station wagon (or van, panel-truck or like vehicle) to its loading position when pulled-down at the back of the vehicle. The tracks are C-shaped in cross-section and the carrier has a pair of wheels adjacent its front end guided therein. Tensioned coil springs may be used to pull the carrier body forwardly. Removable stop means normally prevent the wheels from leaving the rear track ends. Resilient bumpers on the bottom of the carrier prevent damage to the top and rear surfaces of the vehicle. Optionally, roller means can be attached to the vehicle surface adjacent the junction of its top and rear surface portions to protectively and easily guide the carrier body past the junction area.
