Was sitting at a red light waiting, and I see a big Dodge truck in my side mirror comming up beside me. He was going about 35 or 40mph. The light turns green while hes just at my rear bumper. I hit it in first, hes ahead of me, 2nd I start catching up. 3rd gear I blow past him like he was standing still. I took my exit and he kept going. I looked at him and he gave me the :smt023 . Ram 3500 Cummins turbo diesel crew cab, Id say 06-08.
