Went for the 07 with an 06 engine, cuz I wanted a CAT, (no particular reason) along with having the last of the slobber tubes. No special reason and not even sure what Cummins did after that to comply and stay on the road, but definitely don't want to be buying DEF for now and probably never will at my age.
Beginning in 2007, Cummins went with the diesel particulate filter (DPF) to clean up emissions. I don't think they added DEF until about 2010?
