By winterized I assume you mean you will travel with your winterizing antifreeze in your water lines. I picture you dewinterizing by draining these fluids from the trailer's system when you get to warmer climes in Utah. My TT is not equipped for camping extended in sub-freezing temps so I am wondering how your water lines will do if you camp in places like Zion, Bryce Canyon, etc. in the dead of winter. We've been there in December and it's cold.
I will have UltraHeat pads on the gray and black tanks, along with insulation on top of that and heat tape on the sewer plumbing and valves along with insulation. Fresh water is all internal except the low point drains, which I'll insulate. I might put a heating pad under the fresh tank too.
If the temps look like they're going into the single digits or below, I can hook up my mini compressor and blow the fresh lines and add a few gallons of pink stuff to each of the holding tanks.
