Also, remember that just about all the manufacturers use the same AC units in their rigs - all made by Dometic, either a 13,500 btu or 15,000 btu unit. And now most are tied into ductwork. This is fine, but when you have a zillion outlets, that means the airflow is relatively small in each when there is just one AC unit working. Also remember that the cool air must travel thru the ductwork above the ceiling where it's hot just like the attic in your home.
I have a 35 ft Heartland with 2 AC units - one is 15k and the other is 13.5k. That's what's needed to cool it when it's sitting in the sun on a 90 degree day. The larger unit also has the fast cool vent system that lets you bypass the ductwork and dump all the cold air straight down into the living room. This will cool that room in a big hurry.
One last thing. These are 3-speed units. They start on high, then switch to the middle fan speed, and eventually to the slowest fan speed when things get cooled down. I do not know if all have this feature so you might want to ask.
Thank you, GoPackGo for all your helps on my questions!
