Thanks again and I absolutely love the new RVGC complete pinbox replacement to allow me to tow my 5th wheel without the bulky 5th wheel hitch taking up my bed space. Atwood AB-72 pinbox - Gooseneck & kneewall work done in October 2014 Observation After a few years of ownership and about 30’000 km/19’000 miles made by myself with this trailer, the pinbox deflection went from about 12 mm/half an inch static to 25 mm/1 inch static and a bit more dynamic (when driving down the highway). Years of valuable knowledge, and highly recommended if you have similar issues. The adapter makes it super easy to attach your trailer to the hitch even if it’s not perfectly lined up. Then, just attach the adapter to the kingpin on your 5th wheel trailer. Let me tell you, I spoke with two gentlemen at PopUp if I remember correctly their names were Derrick and Chance, those to guys seem to have more knowledgeable information than anyone I’ve spoken with in this industry. This lightweight aluminum adapter sits in your truck bed and attaches to the ball of a gooseneck hitch. A friend of mine said, you should try to call the guys at PopUp Towing as they helped solve his issues.
#Gooseneck pinbox install
Simply unbolt your existing king pin box and install the RVGC in the same bolt holes.

There is very limited on interchangeability, so what you get is what you get. You generally dont have a choice in length of pin box etc. You have basically put a 2 cheater bar on that box. This is a one piece product that bolts onto your existing bolt holes where your king pin box is mounted. Adding a gooseneck adapter will put leverage and force on the pinbox and frame that they were not designed to take, and I have seen failures. The RVGC Gooseneck Coupler is a product that will allow you to pull your 5th wheel camper with a Gooseneck ball without having to bolt on an adapter. Some scratches at mounting plates but otherwise in pristine condit. Attempted to install but found this unit is not compatible with our new 5th wheel camper frame, bad advice from retailer. $1500 Reese Goosebox 20k 94720 gooseneck coupler 5th wheel hitch pin box.
