looked at a 6.7 today
My local dealer has 2 in stock. One was ordered and sold already and the other is a plain XLT with the 6.7. I didn't drive em but the diesel tech said they are sweet. He also told me that they have a new sensor on the pipe that if the truck is not running right then it will just shut it down until the emissions problem is fixed. He said you can add anything to the urea tank but if the emissions are compromised the truck will run on idle only. I didn't know that part about it. Kinda scary, i can't wait to see what the mod guys can do with this truck.
