dual pane windows

I have a lot of experience with double pane windows in three fifth wheels. Six years on a 2000 Jayco Designer, 7 years on a HR Presidential Suite and one year on a 2015 Jayco Pinnacle. I have never had one have any condensation, nor have had any fail. These are all higher end fifth wheels and that may be the reason. In this time I estimate I have traveled more than 150,00 miles. There may be differences due to what type and quality of RV you have and what brand of double pane windows you have.

I am completely satisfied with dual pane windows I have had and would never but an RV without them.
