Ill take my duramax long before a janky Ford 6.0 or 6.4. If you want to pay 40-50k for one of those and then another 5k to have to tear the engine down after you remove the cab good luck with that. My company is getting rid of all the 6.0's and 6.4's we are done with the huge bills on trucks with under 200k miles. We have 5 sterling bullets with the 6.7 cummins they are great trucks.
