There's a reason why Ford drops the 6 speed from 6th to 4th really easily. Both 5th and 6th gears are overdrives. You REALLY don't want to be putting a whole lot of load on overdrive gears. So dropping from 6th to 4th most of the time is actually the right way to climb a grade, ESPECIALLY when towing.

Not quite. The Ford 6-sp trans introduced in 2011 was designed from the beginning to be used only behind the 6.7 L diesel (800 ftlbs of torque @ 1,600 rpm) No way that 420 ftlbs of torque @ 3,000 rpm would ever hurt the trans in any gear.
