I also used the foil bubblewrap on the inside front windshield and the South windows to keep the heat out of alot of the windows. At night, I would put the shade between the day/night shades and the window, and it makes it impossible for others to see in, and keeps the bedroom dark in the morning. I also used them during the winter to keep wind from coming thorugh the window, and the heat in the coach during some very cold Kansas snowstorms. I only had to fill my propane once during wintertime, when others used 5-6 fillups. The foil bubblewrap works well, stores easily, and is easy to cut and install. If I had the means, I would probably do both the inside and outside. Couldnt hurt.
