Im not sure if this kind of thing is allowed on here but we have been fixing foggy windows in fleetwood coaches for about 8 years now. Fleetwoods defiantly are not the only ones with the "FOGGY' issue it was the window manufacture SEGI. Although your window is foggy it can be fixed using your existing glass which in turn makes it  a lot less expensive. we are located in Bend OR, and in the winter months we travel to CA,NV,AZ on 2 weeks at a time trips we have a cargo trailer that all of the work is preformed out of so know need to unhook and drive because we come right to you. if you have any more questions please visit our website    http://www.westcoastrvglassrepair.com/   541-306-8803
