I don't think most people use their trucks this way most days, but it's easy to convince yourself you will.

Aside from the fact that there don't seem to be small pickups anymore, the closest ones I've found all seem to have 4 doors and a really short bed. I can count on one hand the number of times I've had more than one passenger in my Fit, but I frequently need to pick up large items at the local home center or haul things to the dump (old home renovation).

But since most smaller trucks seem like large cars with stubby beds, I settle for having my 4x8 plywood sheets ripped at the store or scoring/folding drywall sheets so I can slide them in from the hatch to the passenger seat.

It's a fine choice, as long as the truck has 4 doors. And the super cabs don't really affect gas mileage much at all.

When I was growing up, my dad had one of those tiny Rangers. There were 3 of us kids. My dad was a part-time plumber and also built our house when we were younger. We'd make regular trips to Lowe's or whatever with him when my mom was working. There weren't even 4 separate seat belts. It wasn't really safe, and it was a tight squeeze that was only possible because we were quite young. Anyways, many reasons why you sometimes need to do both.
