Question:
My fifth wheel trailer has a Lippert 1621 18k pin box on it and Im looking to change it to a Gooseneck. Can you tell me what products will will work with this set up?

Expert Reply:
The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR is going to be your best option as the Gen-Y pin boxes you found are not yet certified by Lippert to not void their frame warranty. You will need the Safety Chain Kit # RP49151 since you are switching to a ball connection.
If you prefer to go with the Gen-Y and are not worried about the warranty then you will need to find the tongue weight of your trailer. The Gen-Y Hitch # GY58GR which is rated for a tongue weight of 1,500-3,500lbs. It is unlikely that you will need the Gen-Y Hitch # GY38FR rated for 2,000-4,500lbs as that is generally for larger 5th wheels. You will need a Safety Chain # GY49GR for either of these pin boxes and I recommend the Installation Bolt Kit # GY86FR incase any of the factory bolts are damaged or become damaged during removal. While you can reuse the factory bolts I have seen them easily become damaged.
