Keeping the Power Stroke guys in mind, we’ve decided to skew our buyer’s guide for this platform to the 2011-2016 “steel body” trucks that we all know and love. With this generation of 6.7L PS, there have been a ton of little bugs in the beginning of it being available to the public, whether it’s a cracked lower charge pipe, a cracked piston from the DEF system overloading the #6 cylinder, or the coolant system helping your transmission overheat.

Unlike last year, the PDC cracked its gates wide open for 2025. No invite-only list, no insider shuffle. Anyone could throw their hat in, so long as they had the guts and the budget discipline to make it happen. What rolled into the staging area at Heartland Homemade Ice Cream was a mix of mad science, backyard ingenuity, and…

Those who really do know their Ford trucks and can differentiate between Ford’s modern trim packages represent the slim segment of enthusiasts who understand that this truck, in this form, should not even exist. To break things down, let’s focus on properties of this truck that can…
