Sold my 96 7.3 with 365,000 on it. My dad bought it new, I got it in 2005 and put more miles on it than he did. Bought a 6.0 Powerstroke 8/2021 with 199k on it and Im at 260k now. Dad has an 05 Powerstroke with 420,000 or so. Dont have any first hand knowledge of a 6.0 with more miles than that, but am sure theres plenty out there. Take care of your stuff and it will go! I have no plans to get a newer (or even different) truck anytime soon unless its for my wife. I hope to keep mine for a long while.
