David Johnson's 2004 Peterbilt 379

Johnson

David Johnson hauls milling machines in Alabama, Tennessee and Mississippi with this 2004 Peterbilt 379. The rig sports a 6NZ Cat marine block with an 18-speed. Johnson added a conversion kit and a drop axle and double-framed the truck. The truck works five to six days a week, Johnson says, and "the rest of the time we are washing it."
