Thanks for the help. I see one Patriot used relatively close to me. I don't think about raising my pin box, I'll look at that, that may make up the difference.
One other option could be a gooseneck adapter. I currently have a Curt "spider" style gooseneck hitch for my 5th wheel rails. I pulled my friends gooseneck trailer with it and it was silent which is one reason of getting rid of the slider hitch. What are the thoughts of using a gooseneck adapter? It seems like it would be a lot more difficult to hook up.
