I like the frameless window idea. My unit goes into production the last week of this month or early April. I ordered the Thermal-pane, tinted, safety-glass windows. Not really sure how they can achieve the frameless capability with double pane windows.
The Thermal-pane windows option really contributes on the overall weight of the trailer (approximately 400lbs extra). If they come frameless, that would somehow alleviate a few pounds.
I guess, we will have to wait and see.
