345 HP Cummins engine with only 17,817 MILES and only 900 HOURS, an Allison HD-4560-P automatic transmission, 18,000 lbs. front axle and 44,000 lbs. rear axles on Hendrickson walking beam suspension with FULL LOCKERS and hub piloted rims. This truck was used a demo truck for a community college which is why it has such low miles and low hours and has been very meticulously maintained.
