Took our 4wd Tahoe Premiere Duramax with all options (basically it's a high country, even the stupid 22" wheels) on a 352 mile round trip yesterday. Averaged 29 mpg and didn't even dip below 1/2 a tank. The other thing, having had the 6.2 and 5.3 in my previous 3 vehicles, is how little this sucker reacts, fully loaded, up hills going 75 mph. The RPM's barely climb... smooth as butter with the mag ride. Best Chevy truck I've owned out of my 2 previous Tahoes and my 2015 Silverado LTZ Z71.
