I agree the 2017+ Super Duties with the 6.2 are fantastic. I have owned a lot of trucks across all brands and this is by far the best I've had; excellent power and with 33's, crew cab 4x4, long bed I average 16mpg, which is 1 mpg off of my stock 2015 4Runner Trial. LOL, amazing.
We used a fleet of Ford 6.2s in West Texas, and it's insane the amount of abuse these trucks took, and many had over 250k miles with thousands of idle hours with no issues. I am a believer.
Now, if I could only stop thinking of my same truck, but with a 7.3 and a 10spd....
