One thing you might want to bring is a tow rope or four-wheel drive. There's always some idiot who gets stuck in the sugar sand of the Pine Barrens (looking in the mirror at one right now). When there was snow on the ground in 2011, I hear even more folks got stuck.
Ninety percent of the time, the road is fine though. I regularly camp at Batona, and almost always bring my 1994 Cadillac Sedan de Ville (well, except that time I took a rental car (with no insurance), got stuck in the sugar sand, and ripped the entire front bumper off the rental car (if a guy named SilentOrpheus offers to push your car out of the sugar sand, graciously decline. His superhuman strength is too much for delicately-made Japanese vehicles). Then a Piney angel in a pickup truck (with a cordless drill) showed up and put the bumper back on in less than 15 minutes. Enterprise was never the wiser!
