While there are similarities between a 1500 and a 3500 and may share similar sheet metal, they are not the same truck. One weighs considerably more than the other, sits taller and is built with heavier duty components.
I know, which is why I said "
I would bet that a 240 hp Ecodiesel gets considerably better fuel economy than a 370 hp Cummins does pushing the same full size truck down the road."
Meaning that even if they were pushing the exact same truck down the road unloaded, I still believe the 240 hp Ecodiesel still get considerably better fuel economy doing it than the 370 hp 6.7L Cummins.

Yes, it can do it, but I'd be willing to bet the mileage difference between a 3.0 Eco and an early 5.9 pulling a 12,000 trailer is pretty similar.
I don't think they would be similar at all. Due to technology like common rail, electronically controlled injectors, intercoolers, and VG turbos to name a few the 3.0L Ecodiesel is able to burn fuel much more efficiency than an early 5.9L. Basically it is able to get more out of each drop of fuel. If you put both in the same truck and slapped the same emissions devices(or no emissions devices) to them and I would bet $1000 that the Ecodiesel would get better fuel economy than the early 5.9L.
