Earlier quoted context omitted.
F-150's aren't the "trucks" he's talking about. F-150s are cars for people who want to feel like they're in a truck. In fact I think by "truck" he pretty much means "trucks not sold directly to consumers." Like a semi, an actual delivery truck, MAYBE an F-450 in a pinch.
Uhm, I can say with some certainty that a lot of North Dakota farmers would take issue with your statement. F-150s are workhorses around here and there is a bit of concern with the 2014 F-150 given the vehicles many uses. I can see this being true in the cities, but it is also sold to a lot of contractors who take it to job sites. The Super Duty (F-450) is actually something to buy if you have a specialized need.
It also seems to be true that many people who own these trucks have no use for them. I wish I had a picture of my high schools parking lot.
