Update on the stock Propex thermostat: Tested it today with outside temps at 20*F. The furnace does fire up when at the lowest setting (which I thought was equivalent to "off"), and heats the camper up to 32*F. Meaning that the stock lowest setting is perfect for not freezing in a light sleeping bag, and the next lowest is a comfy with outside clothes on 62*F.
It would be nice to be able to change those settings, but that's how it is setup stock. I can live with that!
