I have a 2018 f150, XL super crew, max tow package, 3.5 twin turbo ecoboost, 3.55 rear, electronic locker, 36 gal tank. 10 speed, tow mirrors, trailer brake, spray in bed liner, short bed and the only issues were from recalls, other wise not one problem to date.
I bought a RCI complete skid plate kit to replace the crappy plastic ones as I run tons of 2 tracks and they are super for front, transfer, gas tank protection.
I get an average of 19mpg town and up to 25 a few times interstate driving, usually about 20 to 21 freeway though.
