Ok, but most trucks sold today are indeed pavement princesses. For every one you see in the country doing work, there's 5 others being parked on tenth/quarter-acre lots in the cities/suburbs.
My guess is it’s closer to 25%, once you consider people who use a snow plow, haul a boat/camper/trailer etc. Now sure many of these could be replaced with smaller trucks without extended cabs etc, but the choice of pickup truck was still useful.
