I just got through reading about people not getting good fuel mileage in their Rams. I have 2012 1500 5.7L 4x4 Regular cab, I get about 15 mpg city and 21 mpg at 65 mph on cruise. Personally, I consider this pretty good for a full size 4x4. And Im not light on the pedal by no means. Is anyone else getting bad mileage from their Rams?
