I would wager it is only the retail market where the non-crew-cab is nearly extinct. A two seat pickup is a niche vehicle, about as useful for carrying a family around as a two seat sports car.
Not to country folk—kids ride in the bed. Or crammed in the middle if there aren't too many of them and they're still fairly small and you're lucky enough to still have a bench seat.
Doesn't work for suburbanites with trucks, though.
Edit: The ride really wasn't so bad, but it wasn't exactly comfortable, and it was a bit awkward. I recommend riding in a factory installed seat with a seat belt. For safety.
Huh? Show me a single sedan with the rear seat legroom of an F150? Heck, how many come within six inches of having that kind of legroom?
No wonder you think pickups aren't for carrying a family around.
Have one partner drive a sedan/wagon with the kids and another partner haul. A lot more economical too.
In addition you do not need to waste gas if either capability goes unused and the mileage of transporting people won't depreciate the more expensive truck faster.
