Ok am I crazy? (Likely lol) don't these trucks have 26 gallon tanks?

Yup, I usually fill'er up with 24 gallons. What I get out of the tank depends on the conditions I stated above.
Are you guys going by the AVG MPG gauge at all? What does your gauge say? Are the AVG MPG gauges accurate? I'm mostly looking for 09-14 Denali owners' responses with the 6 speed because I'm considering buying a 13-14 Denali, but scared of the MPG with the AWD.
What are your AVG MPG gauge says these days?
Thanks.
My fathers '11 tahoe 4X4 LTZ says 13.8 mpg....just curious for a comparsion to a same gen Denali...
