This invention pertains to cargo transportation, and more particularly to an apparatus that facilitates loading and unloading of cargo from a vehicle. In accordance with the present invention, a retractable bed for vehicles is provided that is simple in design, can be adapted to different vehicle applications and has greater safety and cargo carrying capacity than prior devices. In addition, the invention can be installed or removed by a single user because of it's light weight and efficient design. The apparatus comprises a load carrying transport system having improved structural properties and arrangements for rollably supporting the cargo. The cargo is supported on a rolling deck that is rollably attached to a frame assemble by roller bearings. The frame assemble is mounted to the truck bed. The rolling deck moves along the roller bearings on the frame assembly to move the load.
