The motor is untested. If it is anything like th 6 uh-oh, I will wager a Dodge CTD on the road will beat a 450 in the shop, 8 days a week. The ball is in Fords court to prove it has not laid another big brown thing.
Let's not forget the "Ford #1" price factor and we let you know when you pay for it.
Dodge could pony up with their own electronic brake controller, or like Nissan, a better tie down system. Dodge will sell 10 2500/3500 for every 450. Not everyone needs a big expensive hammer with a maybe motor.
