Word is out on L4 as standard full size pickup engine for GM

Duty cycle big issue for me too, as I tend to keep vehicles till they rather old. Kind of like why I think Ford doesn’t put the eco boost V6 in F250, at least yet. The trucks I use at work are 2017 Ford 550’s with powerstrokes and Ram 5500’s with Cummins. We run them hard all day and night. Typically 7,000 to 9,000 miles we month per truck
