2013 kenworth 660 studio in awesome shape. It has a 13 speed tranny with a new clutch. The motor was rebuilt about 100,000 miles ago it was a out of frame rebuild because the crank needed be replaced. Everything was replaced including injectors, fan hub, you name it. I had them custom paint the motor john deere green and yellow. It is fully deleted and programmed by diesel freak from gaylord mi. With the way it"s set up it"s doing 7.5 to 7.7 mpg it doesn"t use oil or water I run full synthetic in it. I will put all new virgin rubber on it before buyer picks it up. This truck is beautiful and powerful. Needs nothing. It"s still running til sold. It has the nite system electric apu which works great. Bid with confidence this is a money making machine.
