I'm always puzzled about the concern for scratching with acrylic windows. We really have not found it to be an issue. Not one customer has had to replace a glazing due to unresolved scratches. Most people are far more concerned about scratching their paint. 99% of the scratches you might get are easily polished out. The other thing to consider is that if you routinely crash your windows into things that can scratch them, it won't be long before you have a BROKEN glass window. The impact resistance and flexural strength of acrylic is far higher, and you are far less likely to end up miles from home with a gaping hole in your wall. How long would it take to get a replacement glass glazing from Europe?
A severely damaged acrylic window glazing is easily and inexpensively replaced, if you have one of ours. We keep them in stock, and all you need is a screw driver. That is not true of Dometic, because the cost of a glazing from Dometic is as much as a complete window and nobody stocks them. Aside from the remote possibility of getting a scratch, acrylic is SIGNIFICANTLY better in every way for overland use. Here is a link to a good comparison of the two:

Because of the poor thermal characteristics of glass, you rarely see large glass windows in overland rigs. Ever notice that? Coupled with a quality screen and blind assembly (Arctic Tern), you have two dead air spaces, which bring the thermal efficiency of the window area close to that of your insulated wall. You can afford a nice size window and have all the ventilation benefits in hot weather. We carry acrylic because we appreciate all the benefits. I personally would not have a glass window in any kind of RV. I would never sell them. I've spent far too much time in rigs like that dealing with the condensation and other issues.
I'm not telling anyone not to get glass if they want it, but an informed decision goes a long way.
