I'm sure the engineers who worked on the Powerstroke designed its fueling map and transmission shift points to optimize fuel efficiency while towing. I am certain that if the f450 had 3.55 gears it would be using 10th gear at 65-70 mph with an 18 or 20,000 lb rv in tow. The f450 is geared to tow 35000 lbs. Many of us don't even know what a 35000 lb load looks like behind a pickup truck.
