Camco Freeze Ban 2000 Heated Hose (Ranging from $90 for a 12′ to $140 for a 50′)
We stayed in New Mexico for the Month of November and just used an ordinary hose but one night it hit freezing and we lost water. I bought the 50′ version of this hose from Camping World and plugged it in. We hit the freezing mark many times and I did not loose water again. Giving it a 4 out of 5 simply because it worked for me, we did not get down to it’s boasted -20F so I can not comment on that. It has a thermostat and comes on when temp hits 35 and shuts off at 40. Happy with this purchase.
