I know of a number of places here in Colorado where people buy a piece of land, install a well, septic and electricity, then build a pole barn under which they put their RV. Seems most use 5th wheels for this. They often have a storage shed to hold stuff they don't want to haul around. Maybe they have another similar property somewhere warmer for the winter months or this is just a weekend getaway.
One significant advantage is that without an actual house, the property taxes are a whole lot lower. Our "cabin" is nothing more than a 1974 mobile home with a roof over it. Well, septic, electric all installed. Hasn't moved since it was moved in. Nice deck. Storage shed. Trees. Lake view. But because the trailer isn't attached to the land, our yearly property taxes are just $88. A neighbor with a similar sized stick built house pays nearly than 15 times that in taxes.
One has to do some research to make understand the variabilities in the county laws and regulations to see what is possible. Also, you rarely find someplace that is near a major tourist attraction like a national park or even a lake in the woods.
I've thought about it often but can't convince DW to live in a RV all the time. Happy wife, happy life!
