Ram 1500 EcoDiesel Max towing number released

Since the actual manufacture of this engine (VM Motori) is 50% owned by Fiat and 50% owned by GM, I'm actually interested in this. The initial release is a bit weak for my purposes, but it has tons of development potential. It wouldn't take much of a tweak for it to make the power to be a heavy half ton truck, or a 5/8 ton truck.
