Correct Reese Goose Box 5th-Wheel-to-Gooseneck Adapter for Lippert 1621 Pin Box

Question:

I have a 2019 Grand Design Solitude 375res. I didn’t see the numbers on the pin box you listed . Will this 20k goosebox work without spacer kit ? Thanks

I reached out to Lippert and was told you have a Lippert 1621 pin box, so the correct Goose Box for your 2019 Grand Design Solitude is the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR, which has a 20,000 lb capacity.

Additionally, you will not need to use the spacer kit to install this adapter.

I have added a link to a video review for you to check out.
