No way are you going to heat it electrically without shore power which you posted that you did not have. If you are concerned about a tank of water I'm sure you will not like the cost for the taniks of propane necessary to keep the inside above freezing. I would say you have enough 12V power to run the propane heater assuming several 100's of solar. Winterize by blowing the lines out.
