We know that living in the RV this winter, we will have to do lots of insulating to keep us warm and unfrozen. We have been researching and researching what the best ways are to do it. So far this trip we had been filling and refilling the water holding tank and not ever connecting to the "city" water. Well yesterday, we ran out of water in the holding tank and needed to fill up. For the winter we thought it would be better to use the city water and not have to worry about a frozen holding tank. Last night we hooked up our water hose, not thinking it would get too cold. But of course this morning it was frozen, oops. Today we went and bought the heat tape and the insulation, so we should be okay tomorrow. That takes care of our water, now we just need to completely insulate the rest of the RV. What an adventure it is from day to day and season to season.
