Hey Matt! I need you to get me the LCI number and the date of manufacturing off of the sticker where you found the RPO number. If you could comment below with this information I can identify your bolt pattern and find you the correct gooseneck pin box.

@Matt You're welcome! Thanks for getting back to me so quickly! I checked with Lippert and your 5th wheel trailer has a 1716 bolt pattern. The correct gooseneck pin box for your trailer is going to be the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR. You will also need the Reese Safety Chain Kit with Clevis Hooks - 44" Long - 20,000 lbs item # RP49151. These are required by law and are not included with the goosebox. What kind of 5th wheel trailer do you have?
