Looking for trailer parking in the NYC/NJ area

Looking for a place to park an 18' open trailer in the NYC/NJ area.  We're located in Brooklyn but it could be as far as a hour from away.  Since we're blowing most of our money on tires, gas and broken parts we don't have a lot left over but i'm sure we could come up with something.  It would only be for the summer/fall.  In the off season we store it in Michigan.
Thanks
