New York City RV Parking

Heading up to New York City soon. Looking for somewhere to park an RV while we tour. Doesn't have to be in NYC, but close enough to ride subway in. I found Liberty Harbor, but that's campground and plan B. Just looking to park an RV for a few hours, parking lot that will accommodate an RV would be ideal. Just not familiar with the area. Any advice would be appreciated. Thanks.
