For anyone commenting I hope you have driven both the 7.3 and the 6.7! After being a long time diesel guy who admittedly doesn't tow often but need the bed length, I have to say the weight savings of the 7.3 is great. Much lighter to maneuver around as a DD and the ride isn't so springy. Power comparison unladen is Lighter weight with less TQ = heavier weight with more TQ. Just one opinion, but I won't be going back.
