Recommended MORryde Pin Box to Replace a Lippert Rhino Box
Question:
I took a couple pictures just to confirm mine is the Lippart 1621. It has Rhino on it. Just want to confirm I’m going to buy the correct morryde king pin for my 5th wheel. 2023 Solitude 2930RL

Thank you so much for the pictures! That is exactly what I need. Your 2023 Solitude 2930RL has what's called a Lippert Rhino pin box. The Rhino Box, like the Lippert 1621 you mentioned, is a specific bolt pattern and to replace it with a MORryde pin box you will want item # MR55QR.
The MORryde Cushioned 5th Wheel Pin Box item # MR55QR is rated for 5th wheel trailer's weighing between 18,000 lbs and 21,000 lbs. The Lippert Rhino Box currently on your Grand Design has a 21,000 lbs capacity so this will fit perfectly.
I have linked an installation video below that will help you get set up. If you have any additional questions feel free to email me directly.
