2015 GMC Sierra?

[jpeff31787]

our work vehicles are 2008 f150 4x4 with the 5.4.. first time they needed service was at the 120k mark. One is at 192k and the other is around 140k, both running good. I know it isn't the motors they have out now, but should still say something about Fords. We get about 14-15 mpg, and they are loaded down with probably 500lbs worth of equipment in the bed, plus we usually drive them pretty hard.
