seriously? 50's advertising hype as "documentation"? notice it says they test
samples of finishes - in a machine, and
A model of a truck under develpment .... do you really think that dump truck left parked on Cape Hatteras "sometimes in [salt] water up to the bumper" lasted very long? I can imagine what the brake system would look after one time

like the TF advert of the Alcan Highway run, they don't show what the trucks look like a year later let alone 55 years later
and for the part about the loggers 'dependable' trucks, I had a 57 panel that spent it's life here on Vancouver Island as a logging camp ambulance,
this is what happened to the frame in 50,000 miles
