Hello! I wanted to take a minute to give credit where it's due! My wife swore that our neighbors new RV shades made all the difference in the world in how much cooler the inside stayed this summer, so I finally caved and we picked some out. Well, she did all of the measuring and ordering and when they came I was able to install with just a few tools which was another great feature. I thought the women were just exaggerating so they could have some new fancy shades but boy was I wrong! These things must have kept our RV 5-10 degrees cooler in the DAY when were were parked! Glad we decided to order!
