Will the Reese Goose Box 94980 work with a 2022 Grand Design Momentum 397 THS ?

Expert Reply:

Thanks for the picture Mark! Your Grand Design Momentum has a MORryde RPB72-FD, which fits a Lippert Rhino bolt pattern.

The correct goosebox is going to be the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR.

f you don't already have them you will also need the Reese Safety Chain Kit item # RP49151. Gooseneck connections are required by law to use safety chains and the goosebox does not include them.

What are you pulling your trailer with?

Hi Jerred H, I just wanted to confirm that the 22,500K 94980 Reese Products GooseBox will work. I'm opting for the higher pin weight. I see you recommended the 20K. The two vehicle is a 2020 Ram 4500 with a CM Flatbed. Thank You, Mark
