Congratulation on the new camper.
How far south do we need to go to get to an area that would stay above freezing at night?
That's a tough question to answer. As you probably have seen/heard on the news, pretty much the Eastern part of the US is getting snow or freezing precipitation.
To be safe you would more then likely have to be some place in FL.
But if you are only talking of a few days out every now and then, that's a hard one to give you an answer to.
Maybe some of our Southern members will chime in with some info from there area.
