I use mine for work and am often out in the early spring. I carry 110v heat tape with me and wrap the hydrant and my hose. I have had a few freeze ups but just on cold mornings I would leave the faucet run just a bit to keep the water moving. below 0. The shorter the garden hose the better.Make sure you have plenty of propane so the camper itself stays warm and doesnt freeze. The faucets always seem to break first. I have a friend that goes to every home Cornhuskers football game with a MH and when its cold (freezing temps) he fills his fresh water tank with the pink antifreeze for flushing the toilet.Then bottled water for everything else.I have not tried it but other than cost I would think it would work fine.
