Mine just blew hot air all the time - it didn't cycle on and off with its thermostat like it does on air conditioning mode. Before I knew that, I woke up one morning to discover the camper at 80 degrees inside.

The other issue for me was that the B190 was drafty, and the furnace was just much better at making it feel warm inside than even an electric space heater was.

If you have the 190 manual it states that the overhead heater is to take the morning chill out of the camper. At 8 degrees it blows cold air. Not sure how warm it has to be for it to actually provide sufficient heat.

It's just a simple metal-wire resistance heater, I think (not sure what wattage). And at 8 degrees outside, the sheer amount of heat loss through the skin alone could simply be too much for it - not to mention any holes (such as where the plug enters the camper).

On the other hand, the propane furnace provides a LOT more BTUs than the heat strip does, so it can handle ridiculously low temperatures a lot better.
