I truly hope that ford has all of the problems worked out of the 6.0 now, so that they can open it up a little and get back on top. It looks like dodge has a particualarly stout offering. They have already passed GM in the heavy duty market, and it would be a shame if they started taking very profitable market share away from Ford.
i dont think ford was ever on top w/diesel. i love fords, but that cummins is nasty. i would take either one though. they can both haul more that i will ever need. that was a really cool article though. i love reading about the tests they do to those diesel's. i love my straight six but it probably would have blown up on those tests.
