Since we first started looking for a home in Florida I have been attracted to this sort of idea. We saw the pole barn frame for this idea in Port St. Joe, Florida probably four years ago. It was bigger than what’s shown in this photo and was probably for a fifth wheel trailer.
Here’s what I like: The main ingredient is mobility. I can see us moving up to Maine during the summer and fall and then back to Florida from November through May. We can stop where we want both coming and going. I can envision a setup either in Florida only, or at both ends of the migration. In both places we would leave behind outdoor furniture, a grill, some landscaping tools, and such. Add a modest sized shed for storage to the plan in both places.
This would certainly be modest living, but it might be fun and affordable.
