I am going through this very project in my restoration of my 2002 Dutchmen TT right now. It it's quite a simple process and if you are handy then you will have no problems working this out. Just removed the cabinet so you can get to the entire panel. Rip out the old, replaced insulation, replace needed studs and put the new panel back. No special paneling needed. I just bought what was on the shelf at the local hardware store. I'm going to be painting it all anyways so I'm not concerned about it matching right now.
