This is all great news for me, as I wait for my truck to be built. I will be pulling a 25 foot, 11.5 foot high toy hauler, with a gross trailer weight around 10,000# when loaded. My poor 6.0 diesel only gets 9 to 9.5 mph pulling this thing, so I am hoping for 8 with the 6.2. 3 weeks till delivery so says Ford. Can't wait!
