I live in an area where it might be 60 one day and 28 the next. I don't like the idea of winterizing one day and reversing the procedure the next day. And so on. Is there an alternative to this process such as heating one's motor home with a small (or large) heater plugged into house power? I don't have access to an RV garage or storage area. Run the heater on cold nights - turn it off when the day get warm?
You absolutely can leave your RV furnace set to run as temps drop and this will keep all of your plumbing safe. If it were me, I would install small electric heater(s) (with working thermostats) in the water bays and a small electric heater inside the coach to keep things above freezing. Open any cabinet inside the coach where plumbing lines exist to get some moderate air in there as well.
Now, if you are going to get into any really, really cold (15-20 or less) then you might to take more serious steps to ensure the safety of your systems. Keeping the water heater on will protect that storage unit as well but it will eat up a whole bunch of your propane!
