A cart is disclosed which is capable of being wheeled to a vehicle and mounted thereon through a mount secure coupling attached to the cart and a secure receiver attached to the vehicle. Upon secure attachment to the vehicle, the carts undercarriage assembly including wheels are capable of being retracted into the top deck assembly of the cart. Therefore, the vehicle maintains clearance from the road even after the cart is attached. Upon reaching a destination, the undercarriage of the cart is lowered and the cart is detached from the vehicle. The cart is then able to be wheeled away. The cart allows for transportation of loads without the need for the operator to actually carry either the load or the cart at any stage from start to finish or perform any additional steps to safe and securely attach the cart to the vehicle.

The system of claim 16, wherein the undercarriage assembly further comprises: a hydraulic pump foot pedal capable of changing pressure in the hydraulic cylinder pump to extend the pair of scissor arms to raise the top deck assembly. 18. The system of claim 1, wherein the undercarriage assembly further comprises: first and second stow axles running substantially parallel the length of the undercarriage assembly wherein the first and second stow axles each have a pair of front wheels and a pair of back wheels. 19. A method of coupling a cart to a secure receiver comprising: the cart is placed in position with a mount secure coupling mounted on a top deck assembly of the cart substantially aligned with the secure receiver;a hydraulic pump foot pedal coupled to a hydraulic cylinder pump in an undercarriage assembly of the cart receives at least one pump from an operator to elevate the mount secure coupling above the secure receiver;a hydraulic release lever is activated to release pressure in the hydraulic cylinder pump to lower the mount secure coupling onto the secure receiver and seat and cause the undercarriage assembly to begin to rise; andwherein the mount secure coupling has at least one tine which descends onto tine retention slots of the secure receiver during mounting. 20. The method of claim 19, wherein during mounting, at least one latch of a secure coupling lock assembly of the cart is pressured out by a spring to slide along the face of the secure receiver and into place inside an opening on the secure receiver to secure the cart from coming out of the secure receiver. 21.
