Hello Acalkins: I have a Fleetwood Gasser, so my door window is different, however we just had our navigator window panes (3 of them) replaced in Coburg Oregon by RV Glass. It was replaced with windshield glass rather than dual pane glass which will provide good insulation plus never fog. It was not cheap, 600.00 but now I can see through my mirrors again... My wife (navigator loves it too). RV Glass has shops in the midwest and Florida besides Oregon.
