I would probably take the Dodge over the Ford on this decision. I've 'heard' horror stories about fuel systems not being warrantied on the Fords (I would research this very hard if I was in your shoes). The Ford requires DEF, the Dodge does not. I'm not against the DEF at all, and it is almost a given that the Ford in this comparison will net you better fuel economy. Also factor in on how each truck is optioned and are there any missing or extra options that you like or hate (power seats or pedals, upgraded stereo, ect).
Tough decision!
