Long Pine Key Campground (Everglades NP)
Dry camping at $33 a night inside Everglades National Park, open November through May — the natural target for a van with solar and a house battery, since the 35-foot site cap that squeezes big rigs is irrelevant to a 20-something-foot van. Book on Recreation.gov 6 months out; peak-winter weekends go within about a day of release.
