Question:
Can you also post an image with the Reese Gen III Goosebox connected. It is the only oe Jayco has sanctioned with there 5th wheel RVs. A nice addition would be saftey chains in the image.

Yes, I can. I have posted the picture below. The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter item # RP85FR fits Lippert 1621, 1716, 0719, Rhino, and Fabex PB 600 series pin boxes. If you could email me a picture of the sticker on your trailer's pin box I would be happy to contact Lippert and confirm this is the one you need.
Additionally, the safety chains are not included with the pin boxes. You'll need the Reese Safety Chain Kit with Clevis Hooks item # RP49151.

Hey, were you able to confirm with Lippert that the Reese Goose Box was the right fit for your Jayco? Knowing how that turned out could help others trying to match their pin box setup.
