I've been camping in mine during freezing temperatures, so I'll take a stab at these questions:
Furnace and tank heaters will keep it warm enough - EXCEPT the macerator pump can freeze, and so can the check valves at the municipal water inlet and the black tank flush fitting. Those are not heated by the furnace and not protected by the tank heaters, and so are subject to freezing.
Also, it's generally considered a bad idea to run propane-fueled appliances such as the furnace while they're left unattended. Open flames— including inside the furnace— require a real live person to monitor them, lest you burn a lot more than just the propane! Not to mention, what happens if it runs out of propane and you don't realize it soon enough?
Last winter, I winterized FIVE times, because a week or two after I winterized, there was another opportunity for a camping weekend and when I got back I had to winterize again. You probably ought to consider winterizing that way as well. If nothing else, you'll get very good at it, very quickly!
