In memory of my 95 extended cab
There's 2 F series trucks for every square mile of this country. Do you think they are all out there hauling loads and trailers, off roading and actualling being used for truck stuff, or do you think that the vast majority of them are single occupant highway battering rams built to make small men feel big and important?
Remember, 2 per square mile, and that just one series of trucks, from 1 manufacturer, going back just 10 years.
In the absence of hard statistics, I think a gut check on the sheer scale of trucks being sold in the US will suffice.
