No comparison between my heavy duty 2014 2500 and a 2004 Durango.
True for the most part but the engine itself isn't much different. My 2004 has the 5spd auto, I believe yours has the 6spd auto. Both are good but the 6spd is more robust for towing. It should hold up fine. My 2007 Ram 2500 has the 6spd and I now have 120,000 miles on it with no issues.
The 5.7L has been improved slightly over the years but nothing huge. 383hp vs 335hp, torque 383 vs 375. My Durango has a 3.55 rear end. Yours may have the 3.92 which would help towing.
