I call a hitch on a semi a 5th wheel. I call a ball in the back of a pickup a gooseneck. So do they make a ball (adapter)that will fit into the gooseneck hitch and then into the 5th wheel reciever so you can use a trailer with more than one truck? Or could a guy weld the two together, (gooseneck ball and receiver ball for lack of a better term? After a little research it is called a king pin. Has anyone on here ever made their own conversion/
