6.4?
I have a 08 6.7 Cummins, love it and so does my wife. i sold my 91 Diesel for the 08.
Wish i hadn't sold that one! bought it off the original owner. rust free like new interior/exterior. but the wife refused to ride in it, let alone drive it.
nope, the 17 is another Cummins. Like I was saying I was trying to convince myself that the 6.4 would suffice, but the way this 3500 was equipped we made the plunge. Installing the Titan 55 gal tank this weekend:)
