Is it worth while listing campgrounds with difficult access.

I think pnichols is on the right track. Have you thought about a pop up camper? Maybe just get a used one for a couple thousand dollars for those places that you like to go to. Kind of what we did. Our TT was too big and not rigged for some of the campgrounds here in the mountains of NC (and around). So I looked around and found a used pop up that was in decent shape for those trips.
