I remember when Viking bought some of those two story Fords, otherwise known as CL9000. The first ones were like R1, what a rough ride. The second generations were air ride extended cabs. You could run over railroad tracks at 50 miles an hour. That was part of the problem, parts kept falling off. They took a little getting used to with the air ride and power steering. I remember they took one to the TDC's. A driver from another company started to climb aboard, the tractor started to leaned to the left like it always did when you got in it, the air bags made that hissing sound and the driver bailed out. That was funny. We also had that old Dodge big rig in Santa Clara. It turned into a 4 wheeler. Someone changed the letters in front to read DOG which was appropriate.
