It has the 8.2 fuel pincher Detroit diesel motor. It’s a 5 speed with 2 speed rear end that’s in low range. The 2 speed button isn’t wired up. It does have air brakes. Has a gooseneck ball. We only used it to move equipment. Bought a newer truck is the only reason it’s for sale. Been a very good and dependable truck. Asking 3,900 or best offer. # click for number
