When doing demolition work contractors often used their oldest and most rugged trucks. The photos below show a truck typical of a 1960s scene where the dump body was taken off a newer faster truck because it was almost worn out. Putting on this job will probably be the last for both the truck and body.

Notice that the cab protector is much higher than it needs to be; it was built for a new cab that was higher off the frame. The body is the Sheepscot #26115 solid urethane with the load molded in. I machined much of the load out before putting the demolition material load back in.
