I've towed with both the newer Hemi (395hp) and an older 5.9l Cummins (03). Power isn't the issue with the Hemi in a 1/2 ton, it's payload. My Hemi had more reserve power than the Cummins (I can go into more detail). My main concern would be length and weight. I feel comfortable with my current setup, but mine came with a few options that help (longer wheelbase, Air Suspension, upgraded to LT tires). My current trailer is 31' 10" and scales at 5900lbs. I would keep it at or below that on any 1/2 ton.
