8.3L Cummins Diesel engine. 10 speed Fuller transmission. 20 yard McNeilus packer. Reeving winch, lower bar and cart tipper.We are currently using this truck on our recycling route. A new engine was installed in 2009 and has just under 60k miles due to the fact that we had trouble finding drivers that would drive a stick shift. It is an air spring single axle with a pusher axle. The previous owner converted it when the front differential on the tandem axle failed. I find it to be a little unstable with air bag springs and would probably convert it back to a tandem if I was using it as a primary route truck.
