Hi,
You do need to keep the water heater above 32F all the time, so I would leave it on. Sure it will waste a lot of gas, but there is a huge air vent through the center of the water heater, and it can cool to 30F quickly when it is in the low 20's outside. If you where camping, you can turn on and off the water heater, just making sure it stays above about 45F, and not need to run it more than about 2 minutes per hour. Overnight when it was around 19 outside, I would turn on the water heater and leave it on while I was sleeping. Turn it off in the morning, say 6 am, and it would stay above 45 for a few hours. Wind helps get rid of the heat faster.
I have camped in 19 F weather a few times out in the desert. I would run my Olympic Catalytic heater to save 12 volt power, then run the furnace once in a while, to blow heat into the basement and to both ends of the RV.
In your case, it might be good to set up a electric heater to save propane, and set the furnace around 55, leave the cabinets open, and perhaps put the heater near the sink cabinet, blowing in heat to that area. The furnace should run a bit to blow heat to the tank area once in a while.
Your problem might happen while driving though. When I drove 25 miles in 25F weather, my pump froze. I was able to quickly thaw it out with a 800 watt electric heater put next to it and the fresh water tank, with no damage. I guess that driving brought in a lot of air into my basement storage compartments. You might have the same thing happen. Or you might consider using compressed air to drain most of the water from all the lines and the water heater tank, then not worry about it freezing. Just fill the fresh water tank before leaving, and leave the pump off until you need water, plan on running the water heater, and reached your first night's campground.
