If you plan to do the Charlottesville area to see Montpelier, Monticello, etc., be sure to use the KOA. It's about 12 miles south of town. Forget Misty Mountain which is west off the interstate. That owner is a real jerk and will put you in a spot with a 50 amp plug, but only 30 amp going to it. But he charges extra of course. Also, he has sites so tight, we were asked to pull in our slides so our neighbor could pull out. The young couple that run the KOA are wonderful and will accommodate your wishes if possible. But do call ahead. The park fills up most weekends and any time there is a special event at the university.
