This truck was restored about ten years ago and has been kept inside. It has not been used sense the restoration. I do not know a lot about it, but it runs out great. The brakes seems to work fine. The transmission shifts well. The wrecker winches work well. It has the Cummins motor. I took a picture of the sticker on the cab. It tells you the engine size and gear ratio. I think it is a big cam Cummins. The wheel lift on the back goes in and out by hydraulic and you use the winch to pick it up with. This is a really pretty truck. Can be showed off or used. Call with any questions, I"ll try to help what I can 270-792-21twonine.
