The double pane windows that were in our old Fleetwood would fit between the panes on our new Dutch Star. I at first couldn't believe the size of the space, very close to the windows in the stick & brick.
I never looked at the glass thickness on the Dutch Star, now that you bring it up. The difference between 4 years in one and 6 months in the other. I know it wasn't very thick on the Fleetwood.
