Glenn,
That might depend on the warranty--is it any better than Hehr? What is the track record on the Atwood windows--any better?
Not sure the seals on double pane windows can stand up to constant banging, bumping around, for years without problems.

We had all our cloudy Hehrs replaced and after a year all are still clear--the originals were cloudy after 2 years when we bought the trailer but we just thought they needed cleaning. Put up with the fog for 2 more years, then replaced them last year.
