We got out of our 2012 25FB in part because of the inability to cool the trailer in direct sunlight with ambient over 80. We bought a 2015 30' bunk with dual air. Dual air is the only way to stay cool with out a lot shade, insulating all your windows, putting a mister/sprinkler on the roof etc!!! This is more of a problem with the new aluminum skin interiors. The heat just transfers too much. Our old 1979 25 stayed much much cooler. I don't even remember thinking it ever got hot, not like the 2012.
