Norm,
If you want an engine that will give you a lot of miles get a Mack. The fleet I work for (very parttime) run mostly Macks and they regularly get between 700,000 and a million miles on them without pulling them down. That is pulling 100,000 lbs or more a lot of the time. The Cummins don't do near as well. About 4-500,000 out of them. That figure even comes from a friend of mine who is in the "know" at Cummins. Guess that Mack engine is not available or desirable in a PU is it?
I don't recall where I saw this (TDR or Diesel Ram forum maybe?)but someone posted a response they had received from Cummins. In it the excpected life to overhaul was stated as 300.000 for a 12 valve engine and 400,000 for a 24 valve. I would be really teed off I had one and it did not go at least 500,000. Well, I do have tenuous temporary custody of one but that is another story. Even towing most 5th wheel trailers is not much of a load for this engine plus they are cut back some from what they are in a commercial rig. I realize they are not axactly the same internally but still quite heavy duty for the application it seems. There are some guys on the TDR forum who are running some astronomical RWHP #'s but I have no idea what engine life might be.
BTW Norm, I also saw one of the mags did some testing with all the new diesel models and the Ford came out on top overall including power and acceleration wise. That really hurt!
