Thanks for the information! I just spoke with my contact at Lippert and your 5th wheel trailer has a 1621HD pin box. You will need the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR. It is currently backordered (08/14/2023) due to Reese's parent company being bought out and the logistical nightmare the new owners have caused. However, it looks like it will be back in stock at the beginning of December.

If you need an alternative sooner we do have the Gen-Y Hitch 5th Wheel to Gooseneck Pin Box item # 325-GH-8045 available.

Whichever pin box you choose you will need to use safety chains for a gooseneck connection. For the Reese Goosebox you will need the Reese Safety Chain Kit with Clevis Hooks item # RP49151.

For the Gen-Y you'll need the Safety Chain with 2 Hooks for Gen-Y 5th Wheel to Gooseneck Pin Box item # GY49GR.
