I think some of you are overlooking the family economics in truck selection.
Around here, a 4x4 truck of any length or # of doors is a nice way to get you where you need to go in the winter.
If you want to trailer a boat, camper, etc. a truck with short bed is fine. If it has a CC, then the kids and dog go along no sweat. Still room for toys, food, grills, etc. in the short bed.
With a crew cab, your groceries come home in the cab easily, unless you go to the store alone, that isn't likely with a reg. cab. An open bed is not the handiest thing to travel with. Ever stop at a rest area and wonder if your stuff will all be there when you come out?
You can haul a fair amount of trash, diesel&gas cans, gardening supplies, and whatever else you wouldn't want inside an SUV, in a short bed truck.
You can easily haul 4x8 plywood and 10' long boards with the tailgate down. I just brought home 20 8' long PT deck boards and a sheet of OSB in my Sport Trac with a 4' bed for gosh sakes. How often do you buy enough lumber to load up a full size pickup? Get it delivered, it's cheaper than owning any truck
I see the CC short beds as a replacement for station wagons, only better. I don't think people buy them just to say they have a truck. They are pretty good all-purpose vehicles for a family. What other vehicle can cover so many bases reasonably well? That's exactly why reg. cabs with an 8' bed are fairly scarce.
