I wouldn't expect significant mileage increase with a 10 speed behind the 6.2. Possibly under certain high load conditions where it can pull one gear better than a 6 speed, it will be a bit more efficient for the load, but otherwise, there's no advantage mileage wise.
Had 2 different 6.2s. Average about 13mpg in highway/commuting.
Small trailer = 9 mpg.
Big trailer = 8- mpg
Pulled a bit harder with 3.73s than a Vortec 6.0 with 4.10s.
New 6.2s should be very similar.
