The Bollinger has a pass-through opening through the cab (between the seats) and into the front cargo area under the hood. Obviously you can't fit a whole skid of 2x4s in there, but you can fit some really long stuff that pickup trucks otherwise can't really handle.

Edit: the linked page says it can fit 40 2x4s through the pass-through, and 72 sheets of half-inch plywood when the rear seats are removed. Also, with the tailgate down, it can carry 19' material fully supported.

This was actually one of the reasons I ended up going with a (hybrid) RAV4 instead of a smaller pickup. I don't need a pickup for durability reasons (98% of the time I'm on paved surface), but I do need a way to move board as I do a fair bit of carpentry. In the RAV4 I can put the seats down and fit plenty of 8+ ft anything as long as it's not wider than the front passenger seat + center console. Most pickups in the price range I could afford had only 3.5 to 4.5 foot beds, since crew cabs have eaten all of our small trucks, while a few others had "almost" 6 ft.

Major downside of the RAV is I can't fit 4x8 sheets of anything and I don't have a tailgate to drop to make it work. In those cases I just find a friend with a larger vehicle who is available instead, or if I don't need the sheets to be whole I have them ripped at the lumberyard where I bought them.

The moveable wall and full passthrough in this B2 truck looks like a really good deal.

well, for really long stuff, pickup people with 6ft beds get ladder racks. with 8-10ft boards I just leave the tailgate up and put the boards in there at an angle. If I need to get on the highway, a single ratchet strap ensures they don't move around. personally, I had an 8 ft pickup, and I don't really think the day to day is that much different.

With longer stuff - 14-16ft trim, or 20ft sticks of steel, you're basically stuck with ladder racks anyway, so no big deal.

A ladder rack on a small truck vs having a real, functional rack on an SUV might be good either way.

You can, but it will be hanging over the tailgate. Just don't roll over.

I can buy a truck with an 8ft bed from GM, Ford or Chrysler all day long.
