WE bought a 18 month old used 27' 5th wheel to live in one winter while the house was being built. It had two grey and a black tank with exposed under belly. The dealer installed heat blankets on the bottom of each tank and the encapsulated each tank with expanding foam. Then sprayed the outside of the foam with a rubberized texture. The blanket wiring were tied to one thermostat. No issues down to 6 below and 40 mph winds all winter. Fresh water tank was inside the trailer.
