Hello; There isn't a Peterbilt century M100 there have only been 3 made. The first century M100 was a Kenworth W900. The second and third century M100 were both Kenworth C500. Also, I would love to see an M100 on a C500W single steer tri-drive chassis with a sleeper cab, A Knee Boom under lift, and some other customizations that would be an amazing truck. Bit of a jazzy video, I would have preferred more time spent with each type rather than the chopping and changing. However an interesting look at modern recovery trucks.
