Both Ford and Chevy are junk.
Get a real truck, Dodge Ram.
My 5.7L 2014 gets 23 on the highway and 18 around town.
Real steel bed too...
You must not use the throttle.
I have one as well. '14 4x4 ram, 8-speed, 5.7. 19 on the hwy, 16 in town. After 68K miles. I will say, other than the recalls, I've not had an issue with anything on the truck. There are some things that are annoying, some to the point that I may not get another, but the price was a lot less than the Ford that I wanted, and it has more options.
