There are inter-engageable air, electrical and brake connectors on the frame to provide electrical and brake systems to the vehicle extender from the base vehicle, and there is a quick-connection assembly for connecting the vehicle extender to the base vehicle. There can be a combination of a base vehicle and a vehicle extender, with provision for quick connect/disconnect. The base vehicle has a chassis, a body including a cargo bed, engine, tires, an electrical system, an air system and a brake system.
