The top is formed into a "U" shape while the bottom is formed into an "L" shape. The bottom has an opening through which a bolt is inserted which passes into the bed of the truck to secure the first clamping apparatus to the truck. The Cart has an axle which is attached to a pair of wheels. The first clamping apparatus "U" shaped end is adapted to mate with the cart axil. A second clamping apparatus is attached to the bed of the vehicle. The second clamping apparatus has a central locking portion and has a handle attached to the locking portion.
