There was also a triple axle 15K galvanized floating around on facebook, might have been commercial or bluefin fishing pages, not sure, was in Salem NH for $5200 - on face value seemed like a good deal but who knows until you look into it. If I run across it again will post link..To close the loop on the OP. I went back and forth after messsaging the owner. NO title, no lights, no fenders. It has been used for short hauls and yard storage. It looks like a great deal but in the end I decided I did not want another even small fixer project an on my small property in town I would end up with an empty trailer to find a place for during the months the trailer is empty. I'll let the pros keep hauling me. I have a good system now so no reason to get the trailer except it would be occasionally very convenient but otherwise a bit overkill.
That having been said, you could get a great deal on a low mileage one owner DE trailer was the vibe I got. A homemade title, light kit and fenders and she's a winner.
