look. the big 3 trucks are all pretty well engineered at this point. just watch the commercials....their towing capacities are all pretty similar, mileage is all fairly similar, and longevity is pretty similar. its all about the littler features. ride in them, find the one you are the most comfortable with or that has the features that fit you and buy it.

we drove 1400 miles in a chevy 2500 diesel that had 286,000 miles on it. i have another buddy with a dodge that is pushing 250. a guy at work has a ford diesel that has 200+k miles on it.
