Stayed athttp://www.libertyharborrv.com/ couple of years back. had 30 amp hook up and water. they have one (1) common dump station so you have to use some good timing to dump and get out of there. other than that one inconvenience it was a good place to stay. you can walk about 4 or 5 blocks and there is a PATH station to ride under the river and you can get off the underground near times square in NYC.
we always picked up a cab at path station for the ride 4 or 5 blocks back to RV park late at night....!!!!
It was very handy though with nice boats parked across the fence from you and a fair view of lady liberty.
