Dave Burn, out of Lethbridge, Alberta, Canada, hauls mostly cattle with his 2012 Peterbilt 389. The rig is powered by a 550-hp Cummins with an Eaton 18-speed and Spicer Super-40 rears with a 3:73 ratio. He hasn’t done much custom work with the truck other than some chrome gauge bezels and a 12-inch shifter extension. In addition to cattle, he also occasionally hauls fertilizer and grain.
