I rebuilt inside our RV, and ran ducting for the heater along the water pipes so that they won't freeze as long as we don't. I also added tank heaters and enough battery capacity to run them overnight (barely).
Our operating procedure in the winter is something like this:
Turn on tank heaters for grey and black tanks and piping.
Prime grey and black tanks with about a gallon each of RV antifreeze.
Fresh water lines are all inside, and alongside heated ducts - keep the furnace set to a reasonable temperature 24x7.
Keep water heater on.
Use RV normally.

This is in Utah, and is what I've done down to almost 0 degrees. Of course, as those temperatures, I have ice on the *inside* of the single pane automotive windows when we wake up...
