I know these aren't meant for stellar MPG's, but the high teens, low 20's is also welcome.
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.
2002 Tahoe 5.3, about 14-15 mpg strictly highway, 13-14mpg combined.
2016 Silverado CC 4wd 5.3 (basically a 1/2 ton burb with a bed) 16-17 highway bobtail, if I drove slow, 70mph or so.
There isn't a suburban out there that gets 20mpg unless it's downhill!
