JB,
I live in Kansas an am not happy at all with the AC performance. It also appears to be icing up and then leaking down on the floor. Some of the ceiling vents have no air coming out of them at all. Another for my warranty list I guess.
there was a thread about this on the forum, about a baffle not being correct inside the a/c, you drop the interior shroud, and make the baffle vertical and secure and it fixes this.
I spent a week in Vegas temps of 107. AC ran all day but kept it decent. Never went over 81 and I was parked in the sun. It could not maintain 75 but it was still comfortable in the trailer. Got back to temperature about early evening... I think they did a pretty good job it was really hot out. Even in my house AC struggles in the 100,s.
