Abstract: The load carrying capability of a bed of a truck or the back of an SUV is increased by length and weight of the load by including a platform that is movable to the height of the wheel well so that a load that measures say, 4?×8? fits above the wheel well so that the limited space between wheel wells do not impair the load and the wheel wells absorb part of the load. In one embodiment a camming arrangement with a guide rail cam and roller followers attached to the platform place the platform in sliding relationship and raises the platform as it slides rearwardly. In another embodiment a foldable linkage is utilized to raise the platform. Jack can be employed to raise the platform and a brake is added prevent the platform from moving backwards once deployed.
