So you have the 5.0 and 3.31 gears. What cab, bed, and drive you have? Cuz those are some pretty high numbers for your typical Screw 4x4.Other thoughts:
The computer is probably 1 mpg or so optimistic.
The truck runs amazing on E85
@JExpedition07 loves the 5.0 lol
I can get 24-25 mpg at 70 mph all day if no wind and flat.
I also had a great 21 Lariat powerboost 4x4 with 3.73 gears, 18" factory Goodyears & ride height, tonneau cover, 1600 lbs payload, same 38/34 inflation specs.
Powerboost saw less mpg on the same routes at freeway speed (~1-2 mpg less). On trips longer than 3 minutes at lower speeds, it was obviously better. Around 23 mpg computer for the 11k miles I had it.
