What Reese Goose Box will Fit My Grand Design Reflection 150 Trailer?


I have a 2021 grand design Reflection 150 trailer. what reese goose box will fit? I am towing with a 2021 GMC Sierra 2500 with OEM prep.

Since the 2021 Grand Design Reflection 150 trailer uses a Lippert 1621 pin box, the goose box you need is the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP94716. This goose box provides 16,000 pounds of towing capacity and 3,200 pounds of tongue weight capacity. If you need a ball to go along with the box, I recommend the B&W Ball and Safety Chain Kit for Ford, GM, and Nissan Titan Underbed Gooseneck Trailer Hitch # BWGNXA2061. This system will fit the OEM prep in your 2021 GMC Sierra 2500.

If you need help with the installation of the Reese Box or the chains, I linked walkthrough videos that take you through the process.
