Looking at downsizing from our class a to a sprinter and my wife likes the front shades in the Winnebago, but I am not convinced they keep out a lot of light and definitely do not keep out heat. Answers on this thread have confirmed this and I like the Solera 24 R with rear bed and bunk up front. Much more room than the Winnebago and lots of outside storage. On our class A I bought a roll of Reflectix from Home Depot, 4' x 10', about $25, and cut out large panel for the front window of our class a. Reduces heat/ac use and keeps out cold and is definitely room darkening. They also sell it in 2' x10' rolls, so I was thinking I could do that with the Solera and custom cut pieces for windshield and side windows. Any thoughts on this?
