My dad drives a cummins for a living (in his Freightliner), I have the crank with the #6 spun waiting to be turned into a mailbox post(f'n HEAVY, and it did have over a million miles on it). If I were hunting a diesel, cummins or the Ford 7.3 would be up there.
I have been putting 100 miles on the 06 each workday, and 1 weekend day for the last 2 years. Chasing neglected maintenance (some of it my fault) and the fuel made the move for me. She was old and tired, but may make a decent farm truck.it wasn't a great daily, but hopefully the TT v6 is better.
