Double pane windows worth the Upgrade?

So I've heard that the R factor only goes up by 1 or 2 values when you purchase the double pane windows? How much does this upgrade cost Approx? Does it eliminate the moisture accumulating on the inside of the windows when your heating the inside of the RV?

We have the dual pane windows in ours, but without a side by side comparison of two identical units, it's hard to know if it's worthwhile. However, one thing that I did notice was that our 337 was quite a bit quieter than our last unit. We sometimes camp at music festivals, and the noise can be a little overwhelming at night. But it's much easier to sleep in this rig that it was in the last one when the partying gets a little intense.

You know whats funny? I just called a dealer today asking if the unit they have was dual pane. He told me the slight jump in R isnt worth the $2k. We can order one but he doesnt feel its worth the extra money. I didnt even think of noise reduction. Great point!
