Mine (4x4, quad cab, sb) will get 16-18 in town (depending on my foot ) and almost 13 towing a 9500 lb. 5th wheel camper (hand figured although the computer is very close). These figures are at 1900 RPMs- right at 70 mph. A while back my mileage dropped severely but came back. Not sure if I had gotten a couple of bad tanks of fuel or what.
