• Adapter Solution to Convert Gooseneck Trailer to Fifth Wheel King Pin
  We have gooseneck trailer to fifth wheel king pin adapters that would work great on your trailer but it really depends on what type of gooseneck trailer you have now.

• Availability of Gooseneck to 5th Wheel Hitch Adapter for 5 inch Square Outer Tube
  All the Gooseneck to Fifth Wheel hitch adapters we offer have a 4 inch square tube, and wouldn't be compatible with your existing 5 inch square outer tube.
