The shortest bed f150 you can buy is 5.5ft, with a 2ft tailgate, trivially hauling 8ft with just a few inches overhang with the tailgate down, and easily doing 10ft lumber.
Again, I think pickup trucks are idiotically oversized and dangerous to pedestrians, but arguing against them by repeating things that anyone that uses a pickup knows is nonsense is not helping win over any detractors.
