Too bad the Hemi requires premium... Just kidding, I remember the back and forth about this last week. My only concerns with the Ram would be the new engine. Ram has really improved their reputation in the last decade and really seems to be putting out a high quality product.
If I was fortunate enough to be in the market (and could afford!!!) for a new truck, I would have a tough time picking between the two. They both seem to be very capable gassers. I would have to figure out a price, do test rides and come to an agreement with the boss (wife) before deciding between the two. I would guess that either way you decide you will be plenty pleased with your decision!
