This unit has 3126 Cat Motor with an Allison Automatic. Used only in California. This truck runs great but needs some TLC with interior. Power Steering is sometimes hard to turn. Will need tires and a window regulator on the drive"s side. I bought this truck from the primary owner but, did not have the time to invest in it. Buyer responsible for pickup or shipping.
