Very clean fleet maintained unit. Engine was swapped out about 6 years ago at around 500k miles with an engine that had 69k miles. Since then this unit has been serviced every 15 to 18 thousand miles with 10/30 Valvoline oil and full synthetic gear oils every 150k miles. APU was also added at time of purchase helping to keep engine idle hours low. This unit is in great shape and would make someone a great starter truck. Unit is being replaced by a new truck. Truck comes with working Thermo King APU, 70% virgin Michelin drives and Firestone steers. DEF system is working with no issues.
