do a search for issues with dual pain windows. had them on my Bounder. ordered my next Class A without them. when I test drove my bounder the salesman (honest) wondered why bounder had not been sued for them as they could produce a reflection in panes of glass. once he mentioned it I noticed the issue. I would prefer single pane windows with a heavy drape/curtain instead. also found out that thru the glass CB aerials wouldn't work with them. :)
they add weight/cost/and go bad and need repair.
those that spent mega $$$ on them will of course swear by them. I swore at them myself. I also find it amusing when folks say that their current rv with them is so much "warmer" than their old rv without them. not mentioning that the old rv was 20 years old, had lesser insulation, etc.
