Correct Reese Goose Box for a 2011 Forest River Rockwood Signature Ultra Lite


We have a 2011 Rockwood Signature Ultra Light 8286WS Fifth wheel. It currently has a Reese Revolution hitch. I want to replace it with the Reese Goose Ball. Will it fit? Our RV has the Lippert 1621 pin box. That pin box measures 10. What are the dimensions of the RP94716? According to this article, it says the RP 94716 is 11 15/16inch wide. Is that correct? If so, is there some adapters I need?


Expert Reply:

The correct Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter for your 2011 Forest River Rockwood Signature Ultra Lite 8286WS is part # RP94716. This pin box measures 12" wide which is the same for all pin boxes that fit a Lippert 1621 wing set. If you have a Lippert 1621 wing set then the distance between your wings will be 12" (inside to inside). I would verify your measurements but there is not any sort of adapter for this because the 12" width is an industry standard and applies to all Lippert 1621 wings.
