timmac,
Well, I wouldn't worry too much about the fogging issue. It is not limited to any particular make or model of motor home. I've seen Country Coaches, Newmars, Fleetwoods, and more have some and even our present rig, an '04 Itasca Horizon with the 330 CAT has a tad bit of it in the door glass. The tiny, rear window on the drivers side bed room looks really bad. But, it's only about a 10" wide by, 8" tall window and it's certainly not worth the removal, repair and replacement of it.
Our previous coach, a '99 Fleetwood Bounder had both the passenger and drivers side, stationary and sliders fog up. Atwood was going to send new replacements but screwed up the order so bad I canceled and had a local glass company build "Laminated" glass panels for those four windows. It worked flawless, and is still working flawless today, and that was over 5 years ago. WE never had ANY of the condensation issues, noise issues, heat or too cold issues, they performed outstanding.
Anyway, fogged windows are repairable without too much issue. Someday I'll get our door glass done. It the Bounder, which incidentally is an outstanding rig, is what you like, the floor plan, layout, engine, chassis and all, are all up to par with you, then certainly don't let something like the "fogging windows" keep you away.
There are a couple of companies that handle the repairs very nicely. They come to your camp, remove them, repair them and are back within a day or two at the most. Good luck.
Scott
