Hello! New to the group

We’ve had other 5th wheels but never a Grans Design. Just bought a new 2023 Solitude 310 GK-R. Hubby wants to change Moryde hitch out to his Gen-Y 5th wheel hitch. Problem is none of the holes seem to line up. How do we find out which Lippert pin box our trailer has?

Welcome to the forum. You could check the serial number sheet provided by Grand Design, or call them with your VIN. If I were to guess, you have the Rhino pin box.

Welcome to the forum, hope you have a great time in the new coach. As @FT4NOW said, GD customer service is your best bet.

For now we go back with the morryde. No way the holes line up with the Gen-Y

Get the VIN number of your chassis (frame) and call Lippert. They will know for sure.
