I have a 2018 Silverado, 5.3, 4wd, 8' box no cover, I bought it new a few months ago...22.9 ? going 55 the whole time? or is it 2wd?
i get about 18 with a flat bed cover and 17.4 with my cap. 2015 5.3 4 door with 6.5 bed.
Just driving around, I'm staying at 20.4. I've checked a couple times and 20 to 21 is where it stays...unless I'm towing...
I was, and still am surprised at just how good it is on fuel, I was "hoping" for 20mpg, and it beats that consistently. They seem to keep getting better and better on fuel...
