I had a 2002 6.0 w/4-speed and 4:10 gears before my current Dmax and hated that thing for towing. Pulling my 8Klb bumper pull toyhauler through the hills was a chore and spent most of its time in 2nd gear watching the gas gauge drop. I think most who are happy with their 6.0 gassers towing decent weight have to be flatlanders.
Not true and I am happy with my truck. I live in the Pacnorwest and tow with the same truck over some big passes at a similar weight. If you are not worried about MPG let it sign and it does just fine.
In regards to OPs question. I am GM guy but my BIL just bought a 6.4 Dodge. Very nice truck and pulls very good. Wish my truck had at least a 6 speed, but it is paid for... :) If I were looking for a new 3/4 ton or up gasser I would seriously consider any of the Big 3. At any rate. I don't think you can go wrong with either of trucks you are looking at.
