Yes, the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR will replace the 1621 MORryde pin box that came on your 2020 Grand Design Solitude 377MBS. I do recommend double checking the sticker that is on the MORryde pin box for the 1621 as I have seen one off's that will sometimes have something different.
You will also need the Reese Safety Chain Kit # RP49151 since you are switching to the gooseneck ball connection. And the B&W Ball and Safety Chain Kit # BWGNXA2061 will give you a gooseneck ball and safety chain connections if your 2020 Ford F-350 has the OEM Hitch Prep in the bed.
