I have a 2020 crew cab 4×4 with the 5.0 v8 and the 10 speed auto transmission. Got around 3100 miles on it with no complaints so far. Went to Bham and back a couple of weeks ago and averaged 20.4 miles per gallon.
I have same truck with around 3300 miles on it. Bought new in mid September and one two different occassions I have had crazy electrical issues. Once I had no power windows, locks, windshield wipers, radio, etc and after turning truck off and back on it went in to limp mode and check engine light came on. I left the truck off for a couple hours and it reset. A few weeks ago I drove around town one Friday night with no radio because it wouldnt work no matter what I tried. It began working normal again that Saturday and been fine since. Other than those two issue I love the amount of room the truck has. The 10spd tranny takes some getting used to.
