If you don't have a way to heat the pipe of the water spigot you are connecting to then the safest practice is to turn off the water at the spigot each night before bedding down if it is going to be lower than ~25°F. By design these are Frost free sipgots with the handle operating a long rod to open the water valve that is buried under ground to keep the valve from freezing. These type sipgots have valve has a weep hole in the bottom on the output side of the valve that allows the pipe to drain out when the valve is in the Off position. Also note worthy is that if you ever install one of the these type sipgots you have to provide away for the weep hole to be able to drain pipe under ground. Typically done by surrounding the valve with loose gravel to allow it to drain.
Do not ever install one without drainage as the weep hole will get stopped up and it will not allow the pipe to drain out and cause pipe to freeze and possibly burst. Here a link on how to install one and how they work.
Don't forget if it's going to get really cold like in the teens or colder you really need to run your furnace. You need to do so to insure you putting heat in the underbelly/basement of your your camper. You need to do this to prevent all of the water lines from freezing and bursting and to keep the black, gray, and galley water holding tanks from freezing.

Plumber buddy of mine says those aren't allowed/approved for drinking water so I doubt many campgrounds use them. I have 2, 1 outside each of my shops and I know very dirty water comes out of them when you first turn them on.
