My F150 6 speed is nice. The big things are the much better first gear (most of the 6 speeds are better than 4:1 first gear, almost like a creeper gear), and the RPM drops between shifts are less. In a 6L80, first gear is 30% lower, and you don't have the big 1-2 shift rpm drop, compared to a 4L60e.
For what its worth, my F150 (2009 supercrew 5.4 4x4 6 speed) does 10-12mpg towing our jeeps (TJ, or CJ8 with moderate lifts/tires), depending on if we are going 65 or 80. I would say 11-11.5 towing is typical.
Those I know with 5.3 Chevys usually do a touch better, but do run higher RPMs, 11-13mpg towing similar.
ok, back to whatever the topic was....
