Unfortunately, not just Jayco, but most every manufacturer, will practically rebuild your entire unit from the floor up before they'll replace it. It is rare to see a total replacement. When we owned our Tiffin, I saw another Tiffin motorhome get 2 new sidewalls and a new roof. I'll never know how this is cost effective, but that's what most do.
