Abstract: Systems associated with a motor vehicle for facilitating the loading, unloading and carriage of cargo. A preferred embodiment includes a frame securely mounted to a floor associated with a cargo carrying area of a motor vehicle. The frame further included a plurality of rollers rotatably attached to the frame. A deck is supported by the rollers and can slide along the rollers from a stowed position within a motor vehicles cargo carrying area to an extended position with respect to said cargo carrying area. In another embodiment, the deck can be slidably secured to the frame by rails mounted to the deck. The cargo-carrying system of the present invention is generally designed for use in the bed of a pick-up truck, or cargo area of an SUV or Van, and to better facilitate the loading and unloading of heavy materials. The present invention can also provide a working platform and can further include the deployment of side extension wings for extending the surface area of the deck.
