Your best bet for a "wilderness experience" with hook ups will be the Va. - Md. - W.Va. state parks. From my experience, Douthat, Westmoreland Lake Anna, James River and Belle Isle state parks in Virginia would do for you.
In West Va., I recommend Canaan Valley and Blackwater Falls. I haven't stayed in any of Maryland's parks, but there's a mess of 'em close to DC.
State parks tend to be more spread out (space between sites) and offer more in the way of wilderness/nature-oriented activities.
The best way to get help on this (and other sites) is to be specific about your time of year and interests for a particular trip.
