Which Reese Goosebox for Keystone Fusion 357

Question:

Im thinking of installing a Reese Goosebox 20K on a Keystone Fuzion 357. Will it fit that trailer? If so, what products and part numbers do I need to buy and what accessories for a complete installation? i.e. additional plates, safety chains, etc. Will installing that system void the warranty on my trailer?

We don't have specific information as to what pin box comes on specific trailers, so you will want to check the spec sticker on the pinbox itself to try to find a model number. The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter - Lippert 1621 and 0719 - 20,000 lbs # RP85FR you were looking at is designed to replace the Lippert 1621 and 0719 pin boxes, which are some of the more popular pin boxes on the market. If you've got one of those two or the 1621HD you can use the # RP94720. If you don't already have safety chains for your 5th wheel you can use the # RP49151, but that would be the only other additional part needed. Installation of a new pin box will not void the warranty unless there was damage done during installation, so you shouldn't have anything to worry about in that respect.

If you check the spec sticker and find that you've got a different pin box, just let me know what the model number is and I can see if there is a Goosebox that can be used. If there is no spec sticker, you can take some measurements to determine what you've got. I've linked one of our helpful articles on that to this answer as well .
