If a 6.0 is done right, it is a reliable tow vehicle. However it's pretty expensive to have APR head studs put in, they are well worth the added security. That along with deleting the EGR and upgrading to 6.4L banjo bolts, the trucks are good pulling trucks. I've seen many with problems, but once they were corrected(correctly) the owners have had many years of trouble free use out of them. Stock head bolts with any tuner just doesn't work long. If you decide to upgrade it, have a diesel shop do the work, not a dealership. They work will be done much cheaper by people who want to make you happy. Good luck with your new truck and congrats. Fine looking truck!
