Framlesss windows VS Framed windows
Are Frameless windows what I want in a new trailer? I hear they do not have much air flow available?

While I prefer the look of frameless, insulated windows aren't available in frameless that I'm aware of. I do like the sealing with the frameless much better than the frame type.
If I were choosing a TT for windows, I would set my mind on the insulated windows. They make a HUGE difference.
Hehr 6400's are used in Escape trailers. These are 1/2" thick double-pane frameless. These are an option along with the tank heater pads, spray-on undercarriage insulation, and extra interior insulation.
Having said that, the rating of a single-pane window is about R-0.7 and a double-pane with a 1/4" air gap is R-1.7. That's a lot better but still not great. From my experience it mostly helps with condensation issues. I wouldn't go without double-panes, but you will still need a lot of furnace in truly cold temps.
One other advantage of the frameless is that there is no frame to conduct cold inside. The metal frame in most RV windows conducts the cold inside and water vapor condenses on it, often dripping on the inside. That is probably the biggest advantage of frameless over framed in cold conditions.
