Yes, all but the windshield is flush double pane. Apparently ALL Hehr flush windows regardless of what camper they are mounted in will start fogging before they are very old. Newell's in particular are more difficult than most campers in that they use large windows everywhere so they look great from the outside but that requires the interior to be removed to access the window frame screws. I think they have to remove the entire kitchen cabinetry, countertop, sink, etc. as well as the upper cabinets, microwave etc.. Same for the bedroom; bed, closets, drawers etc. will have to be removed, I think. I'm anticipating around 120-150 man hours.
