12 valve Cummins stock motor, un molested, only thing done is 50 horse injectors added. 175,000 miles. Really just broke in. No rust. Was my daily driver… gets 25/26 mpg if you don’t put ur foot into it.. very nice truck. $32K or best offer. Possible trade’s considered. I have a 91 … 12 valve I might sell ..that is set up as a plow truck with automatic transmission. It has 170K on it.. runs like new.
