Florida State Parks are reserved thru Reserveamerica. I’d start right now to nail down some dates. Not contiguously but here and there
Almost all state parks have electric and water and many have FHUs.
Check county parks. Many are on manual system and are under the radar.
John Prince in Palm Beach. Larry Penny Thompson near Miami. Hart Springs County Park has full hookups 50a and cheap.
Lots of private campgrounds around Okeechobee.
