Great Find.
You could get this 6x6 ACCO RUST FREE or is that free rust? for over $500

If I had the $$ and the time, and the room, I would try to save that Wagga truck. It would make a great recovery vehicle.
Sadly, I dont have a lot of either at the moment. (& where would I put it? Not on the street for the vandals.....)
An F15A keeps me entertained.
