Thanks to the design of our Turnoverball Gooseneck Hitch, it works as a versatile mounting system for other types of hitches, as well. With the square base in a round socket, each of our various Turnoverball accessories easily lock right into place. And, when you're done towing, simply remove the accessory and replace it with the upside down gooseneck ball for complete bed access. A hitch when you need it, a level bed when you don't.
