There was about two feet of snow at the higher elevations (above 9000 feet). There was none down where we were camped, at about 6000 feet.
And since the temps never got below about 24 degrees, freezing was not a problem. I have wrapped all of my exposed pipes with insulation, and I have insulated our water tank.
When it gets down below 20 for long periods of time, I deploy my crude but effective hot water recirculator -- it is just a tube that runs from the kitchen faucet to the outdoor shower box and over to the water fill tube, outside the trailer. I then run hot water through the tube. I do this before we go to sleep and at least once during the night. Simple and funny, but it works!
