Question:

I know RP85FR fits on Lippert 1621, I want to know if the Goose Box will fit on the 2 5/16 inch ball installed by Nissan on the 64inch Do we have enough height on the Goose Box and I suspect the5th wheel too near of the cabin. Can you give an answer on that problem.

Yes, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP85FR is designed to work with a 2-5/16" hitch ball. A better way to determine the clearance between the bed rails and pin box, is to install the pin box and adjust it to the appropriate settings.

As most states require a set of safety chains to be used, I recommend the Tow Ready Safety Chain Kit with Clevis Hooks part # 49150 for your pin box. I have attached a photo of how the chains should be used for you.
