We primarily run Kenworth T-660’s and T-680's with Paccar and Cummins motors. The trucks come equipped with either 10 speed or 13 speed transmissions, refrigerators (newer trucks) Tri-Pac APU or Bunk Heater/Invertors (newer). Our average truck age is only 2.5 years old. All of our trucks are set at 68 MPH. Need and automatic? We have options for automatic transmission as well.
