It's certainly possible, but with a lot less steel and concrete you could just build walls and have, you know, apartments. My guess is it's easier to find investors for that, too.
The only reason I can imagine a multi-storey RV park making sense would be to take advantage of some weird zoning quirk or something. But that's a lot of money to throw at what's effectively a legal vulnerability that will probably quickly be fixed.
