Buy for roads and access points, not for trails
A large expedition vehicle drives Florida well and rides it badly. The byways, the Main Park Road, the Loop Road, the forest roads and the Corps lakeside campgrounds all take a big truck. What a big truck cannot do is enter the trail systems: Big Cypress caps a swamp buggy at 8 feet and 6,000 pounds, the Ocala mixed-use miles are the only significant shared mileage in the state, and the state forest riding areas are for machines rather than trucks.
Ask a dealer how the vehicle behaves on soft, narrow, unmaintained limerock with no turning room, and what its recovery points and air system look like. That is the test this state actually sets, rather than a rock crawl.
