Open Question: Are there any campgrounds that can be accessed by car and are primitive in Central to South Florida?

I want to go camping for 3 days or so in an area that is near water so i can catch fish and small game and cook em but where there is nobody else around and i can just grill and sleep in my car rather than backpack and pitch a tent (I don't have the equipment for long backpacking treks). In other words, primitive camping with a car.
A spot that is accessible for a stock 4x4 2011 Xterra
where i can just be a redneck and do what i want with some of my friends (obeying the law of course)
