JMO it seems that trailers are coming with more square feet of glass. Looks nice but makes cooling-heating tougher. The RV manufactures need to look into how much windows buyers really want and look at improving insulation in roofs and walls

While I agree with you, I think a better approach would be to spread the windows out to allow for more air flow without having to use AC or a plethora of strategically placed fans.
As an example, our Prowler only has two windows that open on the door side . . . one in the bedroom (escape hatch/wedge window) and the other just outside the bedroom at the top of the stairs (about a 12 x 12 inch opening), and no other windows that open all the way to the back of the trailer (I know, the kitchen and entertainment center slide is there), except for the entrance door (might be nice to have a slider window in the door).
On the off door side, the only windows are in the slide (two little windows that open about 8-inches, one slider that opens maybe 2 x 2 feet, and a wedge window that is low and doesn't provide much air flow), and no others period on that side of the trailer.
Of course, no front window or one on the front off door side (closet slide) . . .
And now for that huge rear window, which does open up pretty big (the whole off door side of the window maybe 3 x 3 feet), however, the factory supplied window shade only opens up about 1/3 of the way before it gets all crumpled up and won't slide up any further (already had it replaced under warranty and the new one is worse than the original), so having that window opened up at the bottom does nothing for air flow.
Original from the factory window shade . . .
New window shade that was the replacement under warranty from the factory . . .
The mobile repair tech that installed the new shade said that he felt that this type of shade
SHOULD NOT be used on a window this big . . .
I'm just going to take measurements and have a new and different type of window shade made for this window as it seems that all Heartland wants to do is to put another shade just like this one in . . . which is obviously not the answer!

Now, I know it must be tough to try to cover all the bases when designing an RV, but you would think that air flow without having to run three AC units would be a top priority, most especially since many that own RV's camp where there are no hookups, which is supposed to be one of the freedoms of camping (getting away from it all)!
