I have a '77 Airstream Tradewinds with two Vista view windows that are badly fogged and will try Andy's procedure. I was surprised, though, to notice that all the other windows are only single pane windowsanyway. Was that standard in '77? I wonder what the reason was for making the Vista's double paned and the other ones single? Does anyone know?
I think that all of the windows on my 78 Excella are double paned.
I too am planning on trying Andy's "procedure", but just haven't gotten to it yet. If you try it, I would love to hear how it works out for you and if you have any advice. I have 3 vista views which are in bad shape. By the way, Andy told me that the procedure can be used on any double paned window (ie, door window, and the front curved corner windows).
The procedure is to knock out the inner pane with a hammer and some kind of chisel or limited travel punch being careful not to crack the outer pane. The only advantage is insulation between the two and ever then, I think it is hardly measurable. Maybe a degree or too but when it gets that cold....you will likely have other issues to consider. I had a 76 and the best trick is to duck tape the entire inner pane first so the glass doesn't shatter everywhere when you punch it. It was somewhere in the late 70's that they changed to single pane I think, and they are still available if you should break both panes on accident but a "pane" in the ass to change out so be carefull.

Vista views were double paned for strenth and thermal properties. The other windows being single pane was standard, but an upgrade option was thermopane all the way around. My understanding is that Airstream has had tons of trouble with the "thermopain" technology and discontinued it.
I did Andy's trick on my 77 Soverign and it was nice to have the clear panes. You may want to invest in a spring punch that is offered as an escape tool from your car. This is about the size of a pen and has a small punch that will not extend too far so you only break the inner pane. It is not, as I remember, safety glass or tempered glass so it will shatter into a million pieces, hence the tape.

I am doing the ones on my 74 Overlander, found this site which shows it all pretty well. I haven't gotten the new stop material yet, I will call Can-am or maybe Inland has some.
I think we are getting our Andy's mixed up here. Andy who recommends the procedure for knocking the inner pane, is from Can-an - he also sells the rubber insert needed to replace the space left by the old pane, although you can probably use some rubber found at the hardware. Andy who owns Inland does not recommend this procedure.
You also may not need to punch out the inner pane if your trailer is (as I remember) pre 74 - they have a retaining clip that holds a the plastic inner pane in place.
I did not make myself clear. I was referring to the Can AM Andy. Sorry if I confused anyone
I never got around to getting the additional trim, I just put a nice bead of Silicone on the inside and let it cure. I may have been lucky, as I understand the windows can move inward without the trim.
