Winter weather concerns

I currently live in Idaho where winters can be harsh. This will be my first trip this winter with my 2008 Heartland Sundance 5th wheel. I have some concerns about frozen water lines.

My 5th wheel is currently winterized and stored in St George Utah. At the end of December, we plan to head south, pick up our 5th wheel and continue on to Arizona for the month of January. At the end of January, we plan on heading back north. Here's where my concerns begin. We plan on dropping off our 5th wheel in St George again but will have to stop somewhere between Tucson and St George for one night because of the distance. I'm worried about temperatures getting down low enough to cause my water lines to freeze. According to the Climate data, lows are around 32F with highs around 60F where we plan to stay. I'm not familiar enough with the design of my trailer to know if the holding and gray tanks are insulated enough and protected. I've heard of people keeping a drip line going and keeping your dump valves open.

Any thoughts, tips and tricks are much appreciated. Thanks in advance!
  • Some winterized RV's have a heater mounted in the underbelly to keep the tanks and lines from freezing. There may be a switch inside to turn that on if you have it. Otherwise since it is only one night I'd just drain the tanks and lines in Arizona before I left and use the facilities in what ever CG you stop at for that night.

    I spent a winter near IF once (Arco) and it got down to 41 F below once and never got above freezing at night for 6 weeks. That was back in the 1970's tho and I've heard it is not quite that cold there lately.
