Had my first tow with the new 600. Got about 150 miles into a 300 mile trip. with a 25' Grady White behind me when truck started missing badly. Nursed it into the closest Dodge dealer. It showed no errors but sounded like it was running on 5 cylinders. Needles to say, i was extremly disappointed. Dealer worked on it that afternoon and all day Friday. They have no idea what happened to it. Dodge service rep is to look at today. My dealer brought me a 2003 Dually to continue my trip. I havent heard yet today if they have determined the problem. I will let you know.
