we have a 30' X 50' 16' sidewall. the top 2' of sidewalls have clear polycarbonate sky lights. One 14' x 14' door one std auto door. 7' x 9'. We have added the same clear material to one side allat the level of our bus windows for the living room and bedroom. this gives us a 'view' sort of a window on the weather. We use this for spring and fall stops near our daughters area of the country. When we are not there (must of the time) we rent the one side to a family to store their moho in. I would only add a window to the back wall to allow air flow.
