That's absolutely the case. It's a last 30'ish years or so phenomena, and I completely fail to understand it. A weird macho thing? I mean, it is mostly men, and it's 100% fact that "many" (I'd say a majority) rarely if ever use the bed, so WTH is the point? An SUV or other class is a far better pragmatic choice for the majority.
Yup. As a kid, the only families in the neighborhood who had trucks either had fathers who worked in the trades or they had something they needed to tow. Heck my family despite being skiers were somewhat late adopters to SUVs even. We would just pack my dad's Accords with snow tires to the gills. The first SUV they bought wasn't until 1996 when I was in college.
Granted they also didn't really have luxury or 5 seater trucks back then. Most trucks were regular cabs with bench seats for 3.
But, I agree, it makes little sense how popular pickups are today, especially with the gas prices and the interest rates.
