Heated hose

We had a rally one year in Bandera, Tx and it was 15 degrees at night. All I did was slightly run the cold water facet in the kitchen sink. Like I do at home when it freezes. Did not need to run the hot since it is in the RV. That kept the water hose from freezing at night. While some people would unhook there hose at night and roll it up and put it out in the day again. I found that to be a pain in the ass. I liked just slightly run the cold water side of the kitchen faucet.
