I second the Dodge idea.
I bought an '03 quad cab Laramie short box 2500. The 03-04's have the best fuel economy, and no emissions crap. 04.5 and up do.
I've put a fair bit into mine. Gauges, intake horn, exhaust manifold, FASS fuel lift pump, aftermarket tranny, and a smarty tuner. Now for a steering box brace, front end work, sequential turbos, bigger intercooler, injectors, dual CP3 fuel rail pumps, and she will be 500+ horse.
As it sits right now, on 35's, highway 110kph empty, 11-12 l/100km. But when the skinny pedal goes down, she goes, in a hurry!
Dodges are known for weak balljoints and steering box issues. And body rust. Otherwise, a pretty comfy truck, built around a damn good motor.
Real trucks don't have sparkplugs!
