Expert Reply:
The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR is currently the only gooseneck pin box that will not void the chassis warranty on your Grand Design Momentum 397TH. For this reason it is going to be the best option for your toy hauler. This adapter is a replacement for the 1621 pin box bolt pattern. You can verify that it matches your pin box by finding the label on your pin box or measuring the bolt pattern for the pin box. The bolt pattern on the 1621 is 7-7/8" center to center horizontally and 2" center to center vertically. The bolt size is 5/8".
You will need the Reese Safety Chain Kit # RP49151 since having a ball connection will require safety chains.
