The people who were having problems with the 07-09 6.7l Cummins usually had a plugged particulate filter. This was caused by never getting the truck into a regeneration cycle. These people never got into the regeneration cycle because they didn't use the truck ... too much start and stop in town grocery runs and not enough towing going on.

Or being used all day every day, including towing about 30% of the time. Still was a fuel sucking POS (both of them). Yes, they were nearly always in regen because our service area was primarily in town. But I don't think that was the reason for premature water pump failures, turbo failures, and an Aisin transmission failure at 60,000 miles.
