Considering an Ascent. Concerned about MPG

I obviously see a lot of posts about poor MPG, but your real world mileage would depend on how you drive and where you live. I live in Asheville, NC so moderately hilly area. Not Vail Colorado, but definitely not Florida flat either. Anybody who specifically lives in a mountain town care to share what MPG they are getting? I assume on the low end. Thanks in advance.
