Looking for a place to winter

I am not looking to rent but to buy. As far as the ice or snow, neither one is a problem for me as it disappears in a day or two. Being that I will be retired by then, I am not going to be all that worried about being a shut in for a few days! No, after last years winter which was the worst winter in recorded history for our area, what is a half of an inch of ice or two or three inches of snow.
The problem I am having is trying to find campgrounds that have permanent sites that we can winter in. That would be November to April. I am even willing to look at places in the Carolinas and Tennessee.
