I was reading on someone's idea of mounting solar panel on hinges just above the windows of the coach. These could be raised up after you get setup and give you sun tracking maybe. The area around the windows seems to be a good place for portable and movable panels maybe... In travel mode the panels would cover down over the outside of the windows. Once you get setup then they will act like an awning for the window...
Thought that was a pretty idea if you looking for additional room to mount some additional panels....
