Liberty Harbor RV Park is the only place to go with your RV anywhere near the city. Just a parking lot with hookups, but it is very convenient. Very close to public transport into NYC or anywhere else in the area. Around $100/night for W/E, no sewer or cable (but over the air TV is good, as well as cell phone reception). There is a dump station there. Very tight spots, crowded, can be noisy, but it is right across the river from NYC! Don't know what kind of rig you have, but driving anywhere in that area is not for the timid! Heavy traffic, often high speed highways, and during morning or evening rush hours it can be just brutal.
