I am not sure what year the Dodge is but it does have a Cummins. That is why we bought it. I have never touched a 6.2, so I have no idea what a lift line is. Do you have a description?
That is one of the reason I like them. I have heard as long as you take care of them they will run forever and not suck fuel. I have plans for a 6.5 biuld when I get home.
