I have 56000 miles on my 2018 xlt fx4 with Max tow. Avg over those miles as I haven’t reset fuel monitor is 19.7mpg. And that’s with leveling kit on the front and bigger tires. It has plenty of power.
I am not very happy with my truck though. Hate the 10 speed and I have had numerous major issues. Won’t buy another Ford I don’t think
Just bought a camper. Maybe should move to a 3/4 ton now!!!
