The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter part # RP94720 is compatible with the Lippert 1621 SHD pattern. It has a 20,000 lb weight capacity which is the highest available for a Reese Goose Box therefore you will loose 1,000 lbs of capacity as the SHD is rated for 21,000 lbs. That said, this should not be a problem so long the trailer loaded does not exceed 20,000 lbs.
