I discovered one culprit of stealing cool air, and that was the bathroom ceiling vent. When I got out of the shower, and I was wet, my feet were being blasted with cold air coming under the door, because the fan is so strong in the bathroom, it just shoots that cold air right up and out of the RV. So I turned the fan off, and just had the vent open, and there was no more cold air rushing under the door. So that particular situation was robbing all of the cold air that drops to the floor in the RV.
