Since the vents can't be closed i put some foam in two of them to reduce the amount of air and reopened the vent on the AC itself. We normally leave the Fan on overnight to keep the noise out in the morning, but we were freezing the first few nights, so we went with the Fan over the stove and the Fan in the bathroom for now.
One thing that impressed me was the hauling. This trailer is 8 feet longer then my jayco travel trailer but hauls much better empty. Well have to wait a few weeks to see how it hauls with a loaded pantry.
