Back on topic, though. Either will work for towing your rig. Buy the one you like best. With that being said, I kind of agree with the comments about letting some of the bugs get worked out on the diesel. I know there are some videos on Youtube describing some of the issues they've been having. Some are posted by a Ram mechanic.
I've been quite surprised by the capability of my baby diesel, merging is no issue. It's mostly due to the 8spd tranny keeping the engine working in its max power band.
I'm not sure why, but by all accounts of people at the 1500 diesel forum, these trucks seem to by rated very conservatively. Mine has 7850 listed as towing max, and I won't go above the that, but I'm sure the truck could with little problem.
