ours has the covered underbelly with "radiant" heating. E.G. no direct heat vent to the underbelly. I modified that slightly by pulling up one of the floor vents and drilling a 1/2" hole in the side of the vent to direct some air into the underbelly. Then I dropped a temp probe in the far end of the underbelly. underbelly stays well above freezing even in cold temps. And at night we set the heat to 45F, turn in on in the AM.
We've had nights well below freezing, with daytime above freezing with no issues.
the limit is likely the lowest average temp where the furnace can keep up with heat loss during the day and bring the trailer up to temp in the morning.
