One trip I take is about 175 miles round trip. It's about 40% interstate, 40% highway / back roads, and 20% in town with a few stop signs and lights. Also around three pit stops where I shut off the truck. I can average 21 mpg if I behave myself. Of course this is the trip computer calculation. It may be off a little but should be quite close. My truck is a 2017 quad cab hemi 8-speed with 3.92 gears and stock 20-in tires. I certainly can't justify trading it for a 2.7 Ford EcoBoost to pickup around 3 mpg more.
