We do travel with the furnace on in ours. I assume the purpose of carrying water is for flushing?? Even with the furnace on, keep in mind that your low point drain is exposed to the elements and may well freeze. That could and has started the process of icing into the tank itself and also runs the risk of cracking the low point drain tube. I guess it could be insulated to hopefully prevent it from icing, but I don't know how well that would work?? You can carry drinking water in the fridge to keep it from freezing and get a couple of bottles of windshield cleaner to flush with in emergencies. As per the above, our preference has always been to travel with the tanks empty.
