How about some kind of very slow recirculation from water heater back to the fresh tank? Something just to keep the water system above freezing-not much. Downside would be the cycling noise of the water pump but there are quiet circulating pumps @ 12 volt. I suspect it would take limited power and propane because you're only aiming for a bit over freezing..
