Hey Roger. In order to get you the correct Reese goosebox, I'll need the information on the sticker that's attached to your current pin box. The sticker should say date of manufacture, possibly weight capacity, and have some form of RPO, LCI, or serial number on it. If you could email me a picture of it or carefully put all that information where it says Reply to Jerred H, I can find the right gooseneck pin box for you.

Also if yours says Turning Point or Rhino Box on it let me know because those bolt patterns are easy to identify replacements for.

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them. If you're emailing me a picture go ahead and send it directly to the address you receive this response from.

@Rodger Thank you! I just got off the phone with Lippert and your 2022 Alliance Paradigm 310RL has a Rhino pin box. The correct Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter is item # RP85FR. Please note you will also need the Safety Chain Kit with Clevis Hooks item # RP49151 as the gooseboxes do not come with the required safety chains.
