Well you should be able to find out how much is owed with a few phone calls and it might be worth it to pay on it or you buy it and strip the hull and cut it up. Weld over the vin with a few passes on the trailer and grind it smooth, rehab it and re register the trailer as a new one.
As of right now it's really only worth parts depending on how much is owed on it.
