runs and drives. runs a little rough and dose not like to pick up speed some times. was told it could be bad gas. i have drove it around 20 miles got up to around 20 mph, runs real good starting out, then has loss of power, almost like it is running out of gas. was a city plow truck, blade goes up and down, dump bed works. have not tried salt spreader but it will most likely work. has auto trans & air brakes. I do not have a lot of knowledge about diesel trucks, I will answer any questions to the best of my knowledge. not sure on the motor size or brand was told it was a turbo Caterpillar motor. has push button gear selector, seems to be functioning as it should. good tires all the way around. I am about 30 min from Chicago, please call 219 771 9275 to see the truck . would prefer local pick up
