IMO the Dodge has the best styling of the Big 3 currently hands down. The interior on my friend's chevys are merely overly complicated and there's no real value added in most of the extra junk. The only thing I wish Dodge would add to the interior would be a built in pyro, boost guage and a real oil pressure guage...
When looking at trucks, I mostly cared about the components that went into them. In this case I'd been more impressed by the Cummins and the NV5600 than the other makers' combinations. By the time I'll sell this beast for a new one (hopefully 10+ years down the road) then I'll have to start the research once again into who's making the truck the most mechanically sound (best engine, transmission, etc)... To me the appearance is secondary to function. I prefer having a solid front axle over independant front suspension. On IFS you get 4 ball joints you can replace often if you want to do much work or off roading with it, you get to blow CV joints, but when it does hold together you do get a slightly smoother ride... Not worth the trade off for me.
So basically if Dodge didn't have the Cummins, it'd be time once again to evaluate them vs their competition as to whether I'd buy or not. Too early to speculate the MB engine if it ever comes will be junk, and too early to speculate about what the other makers will offer in the future.
