Inexpensive storage suggestions for Boat/trailer?

[logs22]

I am in the process of purchasing a used 14' jon boat/trailer/trolling motor and wanted to see if anyone had suggestions as to a cheap (I.e. Under $100 a month) place I could store the boat/trailer in the Central/north jersey area. Thus far all I have found are traditional storage rentals that offer indoor/outdoor boat storage but the monthly rent is simply more than I could afford and in a few months I would have spent more on storage than the boat itself. I don't need someplace with crazy security since the boat/trailer is as cheap as they come, so I was thinking maybe I could find someone who owns an industrial business who would be willing to let me park the trailer in their lot for a nominal fee. I know some of the industrial lots I see off Rt. 22 in Union & Kenilworth occasionally have boats parked in the back.

Ideally I would like to find a place close to where I live in Union County but since most of lakes I would be using boat at are farther north, I am flexible. If I had a lot that was measured in acres rather than square feet I would just park in the yard however I have absolutely no space in yard or driveway for a boat. Any suggestions welcome. Thanks!
