he Gooseneck Flip Ball Hitch from Buyers Products works like a "fifth wheel" assembly that transfers part of the load to the front axle. It allows pickup trucks and flatbeds to tow up to 15 tons. The hitch is ideal for towing horse trailers, utility trailers, RVs, toy trailers, lawncare trailers, car haulers, and more. The 2-5/16 in. ball assembly mounts under the truck floor and requires only a 4 in. hole in the bed.
