Hi Patybear, welcome to the forum, they are a must have in my book, as posted they really make a big difference when it comes to noise, heat and cold transfer and they just about eliminate condensation, which can be a real hassle. Good luck with your purchase.

Thanks for all your thoughts and comments. Now the problem is the one we really want does not have these windows. This probably sounds pretty dumb. But can we just have the windows replaced with Thermopane. It is a used RV with only 1700 miles. We wouldn't even have to pay regular sales tax since it is from a third party. So it would be worth it to pay to have the windows put in if possible.
