How long had the mh been sitting in the sun before you started out and how long was your drive? Air coming out of the vent is going to be between 20-25 degrees colder than the air going into the return. So if the air going into the unit is 85+ then the air out of the vent may be around 65 and it will take a rather long time for it to get cold even longer to cool the place. Unlike a car, you are attempting to cool a poorly insulated small apartment that is already hot, with lots exposure to the sun to keep it that way.
I have a very old radio shack digital thermometer with a long wire sensor that I stick down the vent. It wouldn't hurt to have it checked though.
Class C's have a slight advantage in this are as the driver/passenger area is more closed in. I've seen some class A owners hang a curtain behind the two front seat to reduce the area that the dash air has to cool.
Hmm yeah I'll get a thermometer and check it. It was very high humidity as well yesterday. The air coming out of the vents could have been 65. I was sort of expecting it to be ice cold like a car.
Also I was towing so the engine was working. Not sure if the heat from the engine could effect the air temperature that would be coming into the MH.
I guess it's not really a big deal to run the AC it does a good job of quickly cooling down the coach.
