Suspension for flat ground that swallows a wheel
Nothing in Florida asks for long-travel damping over rock. What it asks for is articulation at low speed, honest droop, and a spring rate set for the weight actually carried, because the failure mode here is a wheel dropping into a soft hole rather than a hard landing. The Loop Road alone will find the limits of a poorly damped vehicle through potholes and washboard.
Tell the shop the vehicle will spend days in water and wet sand. Bushings, bump stops and shock shafts all live harder in that environment, and a lift that gains clearance while widening the track can push a machine out of a legal width class at Big Cypress or on a 50-inch forest trail. Clearance under the axle matters more than height at the fender.
