Dual pane windows, yes or no?

I have been shopping Challengers and have gotten conflicting recommendations from sales reps regarding dual pane windows. One warned against because of issues with the seals failing, causing clouding. The factory rep assured me that there had not been seal problems and that they would keep the coach quieter.

Anybody have personal experience with these windows?

Thanks!

Definitely get them, much quieter, easier to cool/heat.

are the cockpit windows dual, or just the windows in the house?

Definitely dual pane. Makes a big difference in temperature and sound. Just the house windows.

We had double pane on out last DP. Over the eleven years we had it, I probably replaced half the windows because of leaky seals and window clouding. When we traded it, there were three or four windows that were starting to cloud again. We don't have them on the Gemini, and I can't honestly say I miss them.

What exactly was your last DP?

It was a Tiffin Allegro Bus, but all dual pane windows come from a very few manufactures. I was told the problem with them in motor homes is the constantly changing altitude, which is very hard on the seals. In a house, they hold up much better, since the altitude is a constant. As I said I don't miss them at all, and frankly all RV's have crappy noise and temperature insulation, because the walls are so thin. Nature of the beast!

We didn't get them as an option, a number of friends with coaches have them and swear by them (Techno at the top of the list).

IOE We've been in Death Valley with 3 grandkids, temps over 100 and our coach was very comfortable.

Not sure they are worth the extra bucks except maybe to help dampening sounds on the road.

I spent several years selling and installing residential replacement windows. There is a huge difference between "dual pane" RV windows and residential windows. The RV windows are not filled with argon gas and other additives to keep them insulated and protect from UV damage. They are certainly sealed but do not have nearly the R value of high quality residential windows.

Do dual pane RV windows allow your RV to heat/cool better? Possibly by up to 5 degrees better. Do they keep outside noise out? They will make a difference sure. If you make your decision based on the knowledge that they are only slightly better than regular RV windows then you will probably be happy with them. If you base your decision on thinking they are the same high quality as residential insulated windows then you will be disappointed.

If I was purchasing new and the option was offered for around $500 I would probably add it, anything much higher would be a waste of money IMHO.

I fully agree. We also had double pane on our last coach, a Tiffin Phaeton. We had a bunch of windows fogged and repaired over the 10 years we had it. When shopping for our new coach, we took the "less is more" approach and chose single pane.
