The Reese 5th Wheel Trailer Hitch with Square Tube Slider, # RP30051, has a 16,000 lbs. gross towing weight capacity. It will accept a industry standard 2 inch king pin. It has 10 inches of slider travel to give you clearance between your truck and the trailer.

This fifth-wheel trailer hitch will not fit trucks with beds shorter than 6 feet. It also will not fit trucks with flareside/stepside beds. A minimum 13 inches extended trailer pin box is recommended.

We do have a couple adapters that will convert your gooseneck trailer to a fifth wheel king pin. If you have a round tube gooseneck, then I have the Gooseneck to Fifth Wheel Trailer Adapter - Round, # KPG5-R25-IP. The round tube is 4 inches outer diameter so if you have an adjustable gooseneck, this part will slip right in.

If you have a square tube gooseneck, you could use Gooseneck to Fifth Wheel Trailer Adapter - Square, # KPG5-Q25-IP. This tube is 4 inches square. Both of these adapters have a 2 inch king pin.
