It is simple to explain why they last that long. A diesel engine makes 1000 to 2000 rev's per minute less than a comparable gasser.

Less revolution's= less wear= longer life.

The injection pump maybe won't last that long...

depends on the yr of the dmax, ive heard the early ones having less life expectancy then the later ones, that was in petersons 4wheel drive a few months back. I cant remember the exact reason but it was something to do with the aluminum heads.

I've always wanted a OBS Ford truck with a Cummins and Allision trans... other than the Ford needs a football field to turn around I think that would be an awesome setup!
with an allison behind a cummins, I think the other trucks drop in sales. I looked at Dodge and Ford. Stayed with GM mostly because '09's were disapperaring and by the time my local dodge/ford dealer got back to me, I owned my GMC 3 days. I told them I was getting a truck NOW.
