I think it's more that they think they're taking the better part of both worlds and combining it into one truck. To many the PSD is seen as a weakness, so they take the best part (the Ford truck) and add what they feel to be the best engine (Cummins) and make a really kickin' Fummins truck. I don't have anything against a Cummins, I think they make a great engine, but here we know how to make the PSD work like it should so we don't need to swap the engines!
