I, actually, haven't done much overlanding down here in FL. Though, I know Ocala Nat. Forest has many good trails. My favorite places to camp, really don't require "overlanding", but are great spots. Peters Point Beachfront Park in Fernandina Beach, FL, and Huguenot Memorial Park north of Jax. I suggest bringing your own shade. I'll, actually be hitting both of those spots on the 26th.
