I have to agree with Don and the others about the Dodge Quad Cab's second-row seating. If you have a family, or plan on taking long trips with people sitting in the back, look at the Fords or the Chevy/GMCs.
One of the kickers for me was the powertrain warranty I got on the Dodge. And I love the flip-out, heated tow mirrors!!! But I'm in that 10 mpg range that you're trying to get out of. The RAM 1500 with the HEMI may get better mileage.
The thing I do not like about the Chevy's is the way the dashboards are laid out, and the feeling that there are more plastic parts used in the cab than are necessary. It's a design thing, and some people DO like the way the cab interior is laid out. I'm not one of them. The new Ford F-150 cab (2004 model) is also not something I'm particularly drawn to.
