2017 Pro 4X, 59k, 6" RC Lift on 35s... Love the look, hate the turbo lag/lack of get up and go. Only issue was a heater door actuator went bad and covered under warranty. I do have a small annoying rattle on the driver's door panel that needs to get fixed. Other than the lack of power as compared to a 6.7 Powerstroke, this truck is more than nice enough for me. Gas mileage seems erratic. I fill it up and get 369 miles on one tank and the next will be 270.... I think it may have something to do with regens. Ford seems to be getting way better economy from a bigger badder engine. I did not calibrate for tire size and it seems to be about 3mph off on the highway going 77, it's actually 80. So the bigger tires didn't really affect that much.
