Describes every Dodge and Jeep I have known. Terrible mileage. My '97 Dakota runs about 11-12 according to the computer, while my old '99 half ton Silverado with 5.3 would run 14-16. Both are 4wd and extend cab. My Chevy has hauled my Buell a couple times. Good ramps make a big difference. I know you said you don't need a diesel, but if anyone ever come out with a small diesel in a half ton it would be a good buy, I have a crew cab diesel one ton chevy and it gets better mileage (empty) still. (around 18)It's a four wheel drive and in the real world as a work truck I get like 8-12 mpg
I'm a Chevy guy, so you know where I'm biased, but I've heard good things about Ford's Ecoboost engine, so you may want to look at one of those if you are buying new. I wouldn't consider a Dodge unless it was an older 12 valve.
