Have a 2007 Sub, and it's been a while since I've checked, but I believe it's in the 20ish range on highway driving. The vehicle is used mainly for highway trips, when used around town occasionally I know I don't even look/check.
It get's better than our older Ford Explorer 6 cyl on the highway 19ish.

I recently purchased a 2002 Tahoe 4X4 w/trailer package (76000 miles) and have been shocked by the lousy fuel mileage I'm getting. I average in town and highway around 10 to 12 mpg. It desperately needed plugs (burned down to the porcelain) which I changed, otherwise it runs great. I don't know the rear end gearing other than to say it is stock. While it has the trailer package, it was never used tow tow anything (no hitch!).
What should I be looking at next that might improve the fuel mileage?? I jealous of those getting such good mileage! With gas forecast to be 4.00 plus by spring, I need to get it straightened out ASAP!!!

Here's a knowledgeable, skeptical guy (me) who purchased a 2005 Chevrolet Suburban LS 1500 2wd with 118K miles for my family last year. I hoped I might crack 20 mpg on the highway if I drove nice.
After one year of driving the Suburban up and down I-15 here in Utah, plus back and forth from AZ and California, I am floored at the mileage we can get if we try - easily 20-27 mpg. No lie. Not isolated incidents either. I have checked both on the computer (dash) and verified with manual calculations at the pump. Here is one situation we repeat often: fill up at Maverick in Springville, drive 65 miles north to Centerville, visit family, return, and fill up again = 27+ mpg every time. It's that simple. The formula? Drive nice, set the cruise at 60 mph, stay in the right lane (so as not to bug people). If I drive patiently, even with the A/C on, our suburban easily cracks 20 mpg. When my wife burns through most of a tank just driving back and forth to and from the school for the kids, which is stop and go 8 blocks through town, she'll average 17-18 mpg. I once drove hard for a whole tank just to see how bad I could do, and got 15.5 mpg. That included full-throttle starts and lots of passing, etc.
It's original. Don't ask what's been changed because everything is factory. I take it back, I did put a brand new set of Michelin LTX MS2 tires on it when we bought it, size 245/75 R16. Besides that, I run mid-grade or premium fuel. I change the oil twice a year, and air filter once a year. Just flushed the transmission. Haven't changed plugs or done a tune-up. It's the 5.3 vortec with 3.42 gearing in back, 9 seatbelts, running boards, etc.
True story. We love our suburban.
Note: just drove to Imperial Beach CA with my family, and returned. Driving LOADED DOWN with the A/C going at 85 mph, we averaged about 19 mpg.
