That is one b@dass truck. Was stuck in traffic early one morning near the GW and I got to chat with the owner of that truck for a little bit. I think he said, if I remember correctly, that his truck is the largest peterbilt ever built with something like a 350 inch wheelbase.
He shows the truck around under the name of "Size Matters".

That truck is way over 350 inch which is give or take 30 feet. I used to work for a guy who had a truck that was 25 feet from front bumper to tail lights and this truck is much bigger than his was.

pay attention!!!!!! he said 350 inch wheel base, not over all lengh
