I think you mean Greenbelt National Park. Prince William Forest National Park in Dumfries, Virginia is not that far from D.C. and the public transportation. It has a campground and a concession run RV park where the electric & water sites are $38; full hookups are more. However, the OP said he was looking for places in Maryland and has not answered what part of the state he is interested in.
Yup, my memory is faulty. Sorry for the confusion. I did indeed mean Greenbelt National Park which costs $8/night for senior pass.
