You have sampling bias. I've known
a lot of people who never use their trucks for truck things. "But sometimes I put things in the bed!", acting like there's no way to fit a bicycle or a tent in a hatchback. Many office workers live in an apartment and own a truck. Many of them think they'll end up pulling a boat or a camper sometime (they never will), but in the end still just go to the same bars and clubs and other things in the city.
Spend some time in urban Texas and see tons of people who LARP as a cowboy while commuting from their zero-lot line house to their office job. They'll tell you they need a truck, but probably won't be able to point to a single time other than moving a couch that one time a couple years ago where it was actually necessary.
A vehicle is expensive. But tons of people don't pay attention to their costs. They'll drive around town at 13mpg and spend thousands a year more on fuel, tires, maintenance, and more while never really using the capacity of the vehicle they massively overbought because "it's comfortable". What percentage of people would you realistically expect to know how much they spent on fuel and maintenance on their car over the last two years? How many would have any idea how much that could be cut with a smaller car?
I'm not denying people in rural areas probably have a far higher likelihood of actually using trucks as trucks. I'm pointing to all the people in places like Plano who act like a giant truck is an essential thing to own.
And it's hilarious so many construction workers think they personally need a truck for their job. Some of these are those people I personally know who think they need a truck. They're usually not using their personal trucks to actually do any construction work. Most would be able to go to their jobs and back home in a Civic. When they're at the job site they're using the company trucks to actually do the work. A friend of mine "needed" a truck for his home construction business, a business he owns, but in the end never actually uses that truck as a truck. He drives it to the job site, gets out, hops in his International, and uses that to actually haul stuff.
For any of his employees, why would they even want to just donate their personal truck to someone else's company's use? Probably the most expensive thing they own, and they're just going to put the most demanding and high likelihood of damaging activities on it for their employer's benefit. Nope, instead they often show up in beater Camrys and what not.
And like I said earlier, another friend said he needed a truck because he needed a vehicle that could seat 5. That was the reason. Sure, need a truck for that.
I get so many people on places like HN trying to tell me these people just don't exist or are somehow very rare. And yet most people I personally know who drive massive body-on-frame SUVs and pickups are these kinds of people. Few people I know who own trucks actually use their trucks as trucks. Only a few actually do things like haul salvage engine blocks and transmissions (something where you really kind of do want a bed to crane it in and out) or actually routinely tow something.
