Get a midsize if you're not going to tow anything but still want a truck. Honestly full size trucks are tanks. I park next to a 2500 Silverado at work and it makes my Dakota look like a toy in comparison, and the Dak isn't small.
With that being said, I'd go for the V8 in that truck. It's going to be a dog with the 3.6 and you'll wish you spent the extra for the Hemi. Also, mileage might even be better with the V8 because it's working less to move that thing around.
If you're deadset on the V6, then the Pentastar is a good motor from what I've heard. I believe it was on Ward's 10 best as well.
