This is actually better, because the extended cab means a short bed which cannot accommodate the long channels in the truck. If it’s sticking out the back, it’s a hazard on the road. It could go in the bed and strap the other end to the roof, but then you have a horn sticking up that can catch overhanging branches and whatnot. If it isn’t strapped securely, it could slide off to one side where it becomes a hazard again.

I agree, this person probably doesn’t need a pickup truck. But they have the materials loaded correctly.
