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.  (Check out our other auctions for the best price on the B&W Turnover Ball!)

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 "V-19" 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.

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.
