A load bearing carrier system for carrying additional cargo in the vehicle or on the carrier itself. The support system increases the wheelbase of the vehicle to stabilize the added weight and extended weight out the back of the vehicle at high speeds. The load bearing structure attaches to the tow vehicle at trailer hitches or directly to the frame of the vehicle. The system includes a receiver hitch or a multiple receiver hitch beam attached across the rear of the tow vehicle attached to the tow vehicle frame. The carrier mounting beam has trailer tongues pinned into said receivers and the attached mounting beam of the carrier has vertical beams near each end to mount the springs, air bags, air shocks, load bearing air cylinders or spring enhanced shocks type of suspension, the cargo platform and attached trailer hitch. The mounting beam has pivot beams to mount the spindles, hubs, brakes, wheels and tires. The suspension forces the pivot beams, spindles or axles, hubs, wheels, and tires to the ground lifting the carrier, cargo, cargo deck, truck, and trailer hitch attached to the cargo deck upward in a load bearing manner.
