I agree, anything new doesn't really get as big of a benefit, from a towing standpoint, as the older trucks. The mileage is good, especially considering the power.. yes it could be better with less EPA but that's a different topic.
I am right at 415/850 to the ground but never use it all, even up 4-8% grades running 55-70 mph at 20K GCW with a LOT of wind resistance. Once I drop to 5th and settle at 55-65 I don't ever seem to go over 80% load and usually run around 60-70% on a 6-7% grade.
The OEM power, combined with the ratios of the double OD (what I really want is a double OD 7 speed manual) there is PLENTY of power for nearly every load.
