Our first 5th wheel had them. This one does not. I notice no difference. We decided to save on the cost and the weight and glad we did. By the way, when they fog up it is expensive to have them replaced.
7 years....no "fogging up", no condensate, no repairs, no issues. Again, I've had both, if nothing else, there IS a difference in noise coming out of my 5er being dampened and noise coming from outside in is dampened to some extent...
oh, and as far as paying extra....I purchased my 06' 5er brand new off the lot late 07', unit was discounted substantially...don't feel I was charged "that much" for the dual pane windows....if anything at all for that matter
