Heaters for fresh, grey and black water tanks?
I have a new Rockwood Mini-Lite 1901 that I'd like to use in mild winter weather, eg. Fall at 5,000 ft. elevation. Rockwood offers and Camping World is happy to install heating "pads" that go on the exterior of the fresh, grey, and blackwater tanks to keep them from freezing in moderately cold (i.e. below 32F but not extreme cold) weather.
Since the 1901 does not have an enclosed underbelly and water lines are exposed, the heating pads on the tanks alone does not make a lot of sense to me.
Anyone out there looked into the problem of using the smaller Rockwoods when overnight temps can go down into the 20's farenheit?
