I own a cummins and a powerstroke. They are both great trucks. The tranny on the dodge is much weaker but the cummins is great. It is good that the cummins has a new injection pump it costs about 1000 dollors to replace. The daily operating costs are about the same for me anyway. The dodge interior is not as roomy or comfortable has the ford. Good luck i like the Ford better but i think either way you will be happy.
