Love those old Internationals. We had an early 70's 4wd for a fuel truck on the farm. It was pretty worn out and would oscillate in the yaw axis while driving in a straight line down the road. My current airplane hauler is a 2000 Chevy extended cab with a long wide bed. It was my dad's last farm truck. I expect that Flyer in OKC experiences the same thing that I do. Long wide bed trucks tend to be actual working vehicles. Between farming and oil field they tend to get used up rather than being sold on.
