Gooseneck to 5th Wheel Adapters to Let 5th Wheel Hitch Tow Gooseneck Trailer

Question:

Hi there, I need an adapter so that the fifth wheel in my truck works with a 2001 Sundowner Gooseneck trailer. The person that physically has the trailer at the moment not on my property since I literally cannot move it yet! said that the tube was 2.5 inches in diameter and round, but it looks like most the ones you all sell are 4 inches? Is there a 2.5 inch one or maybe 3 if she didnt go outside to outside on your site somewhere that Im overlooking? Thanks!

Expert Reply:

We offer all sorts of 5th wheel and gooseneck hitch adapters that allow towing one type of trailer with the other type of hitch. On the linked page you can see the adapter from Wallace Forge that lets you tow a gooseneck trailer with a 5th wheel hitch, part # 2085295. This provides a 2-5/16-inch gooseneck ball to couple with the trailer. This is half the weight and much smaller than the Bulldog part.

Adapters that work on the trailer side, like the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289640300, fit standard round gooseneck outer tubes and replace the inner tube. This part has an outer diameter of 4-inches so it will fit an OUTER tube that has an INNER diameter of 4-inches.
