If you have dual pane windows have you had issues with moisture getting between them? If you had single pane in your previous RV and dual pane now are they worth it? Thanks
Here is a decent article re: this discussion. Seems that the "fogging window failure" issue is more of a problem in trailers that don't have the same suspension that motor homes have. Trailers ride rougher, vibrate and flex more which is the reason for failure.
