Interesting! Thanks for posting.
Well, that confirms that the frameless windows will be thermal. Good! And they'll probably look like what Karen posted as that type seems to be on a vast majority of RVs these days. Most are awning type, but you can also get them with a slider window.
I found this link when I was cruising around, looking for info on frameless RV windows:
Guide to RV Windows, It's All About the Glass
Edit: They're listed on all of the trailers (least the windows; I didn't check for the cubbies, but would assume so).
