We just purchased a new Classic Airstream and with several weeks worth of use have discovered that ALL the windows have a gap near the top and bottom of where the two levers must slide to open and close the windows. In case this description is lacking, the slide openings are located to each side of the window and have to be there to lever open each window. It's both the tops and bottoms of these slides that have gaps and each gap is about two inches long and maybe a quarter inch wide.
Engineers must not live in mosquito country else they'd know how little space is required for bugs of all descriptions to enter.
Isn't there some way of blocking these bug doors?
