We use solar screens on the outside, when camping, which gives you privacy during the day time. When it gets dark we use a piece of the 4'high, foil covered, bubble wrap, that we cut to the length of the windshield and use on the inside. This also adds additional insulation from cold or heat from coming through the w/s area.
We have been using the same piece for 3 1/2 years. The curtains are only pulled far enough open to cover the side windows and door.
I originally bought the bubble wrap for use while the MH was stored next to our house. I wanted to keep the Florida sun out and thought the curtains would deteriorate from the constant sun.
