Hey Gerry, welcome back. We will definitely have a Gen-Y Executive pin box for you, but they aren't make and model specific to the RV, so I will need a bit more info from you. Specifically I'll need to know what pin box size or bolt pattern you have now.

Your current Curt pin box may have a sticker that say the size (Lippert 1621, Lippert Rhino ect...), but if not, there should be a manufacturer sticker up on the side of the pin box brackets that shows the model number/RPO number/serial number.

For example, the Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY76PR replaces the Lippert Rhino pin box. This will be the correct model based on your GVWR, we just need to nail down that pin box size.

If you can send me that info, I can determine exactly which replacement pin box you'll need.
