That's interesting, because we were out in cool weather this past weekend with our 2006 8356, up in the NC mountains. Temps on New Years Eve were below freezing and we were very comfortable. Tuesday night, we stayed at WW in Greensboro, where the temps were in the mid 20s with winds of 25-30 miles per hour, still comfortable (at least temp-wise). The only real problem is the fact that the fans tend to be a bit noisy, so we only run the front unit when sleeping. Also, I'm concerned that the fans will run the house batteries down overnight, so I run the gen set if not hooked to shore power. I'd rate the heat system in our coach as pretty good.
