Ours has been repaired twice and is now fogged again. The door window is subjected to more vibration intensity via its repeated closings, sometimes wind-assisted or via an overly aggressive guest or young child. If you’re lucky the glass isn’t etched and just needs polishing and seals reset, but that’s rare. Normally etched glass has to be replaced with custom-built panels… not all doors are as alike as you’d think, so fitted standard glass sheets aren’t just sitting in warehouses awaiting our needs.
A company in Vancouver, WA, does the laminated thing which would do away with the fogging issue. But they build an entire new window, not just replace the glass, so it costs about twice as much, ~$600-700? And they don’t install. So you have to remove the old window, make them a precise template of the opening, dispose of the old assembly, and install their new one yourself. For many here I’m sure that’s no big deal and they’ve replaced windows before. A helper is advisable, which I wouldn’t have, so I had to think through a safe methodology to accomplish it myself if I was to go that route. Laminated isn’t quite as insulative as double-pane with argon though.
Steve’s advice to find yourself a local RV Glass Solutions outlet is likely best and is what I may do, although the one that could do ours is 100 miles away. The glass company in Bend that did ours twice, as via Beaver Coach Service, no longer is their go-to guy. Probably good reason for that judging by our experience. So we may have their new glass outfit do it on our next service visit to BCS, and hope it’s a longer lasting repair than the prior ones.
