Rocco,
My best guess is that it is luck of the draw as to what you get unless you actually go and visually inspect them.
While I was allowed to roam freely in the storage yards they would not allow me to give them a good going over since, at that time, they were still scheduled for rebuild.
My unit no longer has operational control over Shelby so I have not been there for several months.
The decision to sell them off was made just before I quit going down there.
There is one yard down there that has at least 50 wreckers and a bunch of dump trucks in it.
The DRMO guy told me that there was a big debate as to whether to sell them whole and have to provide paperwork or scrap them and send them out in pieces.
The last time I was there they were cutting up several bridge trucks and sending them out in dump trucks.
I hope they realize they can make a lot more money selling them whole.
