I had a perfect opportunity this morning to capture the piece de resistance when it comes to semi-stacks on pickup trucks. On the drive into work this morning there was a 1-ton Goat (of course) with a single large ~8” stack coming out of the center of the bed. Let me repeat that, the stack was in the center of the truck bed. You know where you would put a gooseneck hitch in a truck bed? That general location is where this guy had is exhaust exit. I reached for my phone to document this glory but was too slow. He laid down a bondesque black smoke screen and POOF! he, his stack, his plastic nut sack hanging on the receiver, and his giant Cummins rear window sticker were gone.
