LOL. Mid teens, bobtail, highway cruising IS stellar for a 6.0 gasser.
Anything over that, you're dreaming and less than 15mpg is where it will be for combined, city/highway.
That I believe, but also considering the 1500/5.3/3.42

There isn't a suburban out there that gets 20mpg unless it's downhill!
I guess it depends on how you drive it. When I say 20 MPG, I'm talking filling up and jumping on the highway,prob cruise 65 ish.
Really the only reason I threw that in there was we rented a 2015 to go to the beach and it would get 20 on the highway all day long.
I just don't know how the pre 2015s were with AFM. I'm fine with mid teens for the 6.0 2500.
