double pane windows worth it?
Looking for a new 5er. One dealer said that the double pane windows only increase the R insulation factor by +1 or +2. That may be, but I also thought the double panes decreased the water condensation on the insides when heating the rig. I've also heard they make the rig quieter? What are your thoughts on Double pane windows? Worth the upgrade cost? Our current 5er has single pane windows.
