Of the area from W Virginia to Maine, if you have never been to the northeast, I'd say the Maine coast is a must. Bar Harbor and Acadia National Park (NP). Stay at Bar Harbor CG. Boothebay is nice (Shorehills CG). Day trips to Rockland and Camden. You can see the Kennebunkport and Ogunquit area from Bayley's CG in Scarborough. Portland, NH is great and you could stay at Wakeda CG in Exeter, NH (ask for one of their very long pull thru's.
The Lakes region of NH is fantastics. Meredith Woods CG in Meredith is good. From there day trips to Franconia Notch and across the Kancamagus Highway to Conway, NH.
The best CG to see Boston is Normandy Farms in Foxboro, MA. Take rt. 495 around Boston to Foxboro. Boston is a great walking city. Take the train into it from Normandy Farms.
From there I would head to Lake George, NY and stay at Lake George CG. A lot of history in that area. Lots to see and do. You could take a day trip to the Vermont Teddy Bear Factory and Ben and Jerry's Factory.
I would spend my time between Lake George and Bar Harbor and skip the rest of the northeast if this is your first trip.
