Dual pane windows.....add weight? Reduced CCC?
How much weight do dual pane windows add to a 5er over single pane? Seems to me that if they add quite a bit of weight that reduces your CCC.

Dual pane windows are pretty much standard around here. Except for more basic 5er's, dealers don't stock units with single panes anymore. In the great north wet, wouldn't have anything but dual panes.
