Welcome to the forums!
I use mine year round in the Carolinas and Virginia (well I was until I tore it apart
) Not sure of your tempature extremes where you are. But as long as you have the furnace on you are good down to the mid 20's with minimal preparation. If you don't leave it hooked up you can do what I have done with my popup for years. We would winterize around the first of October and just use it without dewinterizing. We would take bottled water for drinking and use the campground bathhouses.
I am sure other people have their own ways of dealing with colder weather.
