Use of my Boat Trailer (for boat up to 21ft) exchange for storage

I would like to make a deal with someone who has space in their driveway in the city for my Boat Trailer(just trailer,no boat). In exchange, they can use my trailer for servicing their boat or take on short trips fishing etc. The trailer can take up to a 21ft boat. It is a single axle, and can take up to 6000 lb towing capacity. It requires a 2"x2" hitch and a 2" ball. I use a 4000lb hitch on my suv to pull the boat. If you are interested please send me an email. Thanks Peter
