What do you know about the "Azdel Composet Sidewalls"?

Thanks for the posts, Everything I've read had nothing but good things to say about it! It's also a much more expensive product than the typicle sidewall for a motorhome! That says something in itself, what coach builder would put more money into something that wasn't better?

I also found this product has been around for a long time, so it isn't like it's new and untested! I first wanted to know If I should stay away from coaches that have it? I have found it's good to persue coaches that have it!
