Reese Goose Box For a 2018 Grand Design Solitude 377MBS


Will the 20k Reese box work on my 2018 Grand Design Solitude 377mbs?


Expert Reply:

To confirm that the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94720 will fit on your 2018 Grand Design Solitude 377MBS you will need to check your bolt hole spacing. The information I can find on the Solitude 377MBS shows that it uses a 1621 pin box bolt pattern with bolt holes spread horizontally 7-7/8" on center and 2" on center vertically. If your measurements are different please let me know what your dimensions are or I can check with the Lippert frame tag on your Solitude.

You will need a Reese Safety Chain Kit # RP49151 since you are switching from the king pin connection to a goose ball connection.
