For years there were no "kits", you just fabricated your own mounts so that is still an option today. Don't know what you are going to be hauling/towing but if it requires a goose neck the FIRST thing that needs done is brakes on the truck and a must on the trailer. In my younger (foolish) days I towed a race car all over the U.S. with a 53 3600 and a V8 engine. Would PULL anything and STOP nothing. Seat cover was covered with butt bite marks but shear luck got me through with no bent tin.
