Towing with a fifth wheel hitch is OK, but you can forget about using your truck for anything else! That massive hitch is always in your way. A Fifth Wheel Adapter from PopUp gets that colossal hunk out of your truck.

An RV Adapter from PopUp lets you tow your travel trailer with any standard 2 5/16" gooseneck hitch ball. Use it with a PopUp Ball or a Flip-Over Ball and you can pull your RV trailer and still have a completely smooth fully usable truck bed anytime you want it.

To make your towing experience better yet, these RV Adapters are fitted with a PopUp GN8 self-latching coupler. This coupler latches when the trailer is lowered onto the ball. It also has a molded hitching guide to make coupling easier. To uncouple, you simply pull a release cable located near the trailer jack handle. The GN8 coupler has a rating of 28,000 pounds.

The Adapter is held securely to the trailer king-pin box with a strong king-pin clamp. It also bolts to the king-pin box for additional stability. The installation fasteners provided are Grade 8. Installation takes about an hour.

The unit is built strong with a gross trailer weight of 24,000 pounds and a gross tongue weight of 6,000 pounds.

Adapters are furnished with a long lasting powder coated finish, and comes 100% complete.

A Testimonial from a Very Happy Customer

"I researched the available 5th wheel to gooseneck adapters prior to my purchase and was most impressed by the PopUp Brand line of adapters. When I got the unit & installed it, I was still even more impressed by the quality & Workmanship of the unit, it is better than I expected.

In today's throw away world, it is good to see a company that delivers more than expected, Young's Products certainly has.

I have already recommended your product & am sure to many, many more times.

Thank you for a fine product. James from Newberry Florida

P.S. It works super too!"

When you uncouple, the Adapter stays with the trailer giving you full use of your truck bed for the other jobs you need to do.
