Question:

We’re looking at a 2021 Alliance which is rated 18,000 lb+ and appears to use the Lippert Rhino-box. Does the MORryde MR24MV handle the Rhino-box conversions at this heavy end?

Expert Reply:

Erika, absolutely. The MORryde GooseTech model # MR24MV is designed specifically as the gooseneck-adapter replacement for trailers with the Lippert Rhino pin-box pattern rated at 18,000 lb+ GTW. You'll also want Safety Chains to be safe and legal # GY49GR.

Because you’re in that heavy end category, you’ll want to double-check that your Paradigm 385 RD indeed has the Rhino-type pin box (sometimes manufacturers change patterns throughout a generation of RVs). If you confirm the Rhino box, # MR24MV is the correct path. I've also attached a help article to show you how to check.

What tow vehicle are you using here?
