I'm thinking about getting the heating pads but I was thinking, I have three tanks, grey, black, and galley. Each are about 20-30 gallons. What if I just put 15-20ft heat tape, taped to the bottom of the tanks, then wrapped the reflective insulation on top of it, do you think that would be sufficient?
Even the heating pads are a bad idea unless the outside temps NEVER get below 30F for more than a few minutes.
It might help to know where you plan on spending the winter but regardless, most RVs that are marketed as 4 season, are still going to have frozen pipes and or dump valves in true winter conditions. Best, safest thing to do is use a porta-potti and pack water in portable containers, heat water on the stove and sponge bathe or use a primitive portable shower, drain grey tank immediately after each use.
