It's probably not what you really want, but there is camping (or, perhaps more accurately, overnight RV parking next to a picnic table) at Floyd Bennett Field in Brooklyn. There are no hookups or dump station Just getting there with an RV would be something of an adventure in itself, I suspect; the most obvious route via the Belt Parkway is not an option due to typical parkway vehicle restrictions.
It looks like it's about a fifteen minute bus ride to the subway, or an hour or so walk. Biking also appears to be reasonably practical at first glance.
It would be about a 30-45 minute bus ride to the nearest subway stop (Flatbush Avenue terminus for the 2 and 5 trains which are Manhattan West Side and East Side lines respectively) via a Green Line bus which only runs about once every 30 minutes during non rush hours. The walk is much longer of course though pleasant in a "am I really in NYC?" mode. You'll pass a marina, a golf course, and have to brave 1 highway entrance. Street lighting is more in keeping w/ further upstate NY and the sidewalks are over run with growth so at times you'll have to walk on the parkway. Randazzo's Clam Bar is right off the highway and makes an excellent repast.
Despite living in Manhattan, I know this area well, as I worked near Brooklyn College, for several years, and maintained a garden plot there for a time. Fertile land, rotor-tilled annually w/ manure donated by a nearby NYPD horse stable. Unfortunately, I had to give the plot up as it really was too far from my home in Manhattan. Still can recall the smell of salt air and greenery in my nose though:).
From an RV POV you'll have to drive on Flatbush Avenue for most of the time and the throughway is a bit harrowing though pretty wide as NYC streets go. In the West Indian community, Flatbush, is known as "The Capital", since it passes through several communities dominated by one Caribbean group or another. Great eats if you can actually find a parking space that isn't being double parked before reaching Eastern Parkway.
I do hope the city, state, and Feds come up with a viable and sustainable plan to get RVs to the park but it really isn't easy as things stand now unless you are driving a small truck camper.
