The 6.2 gets the same mileage as any HD gasser and that is subjective based on, well, all the factors that go into mileage.
3.73 6.2's both of em averaged 13+ mpg commuting/hiway/city mix.
Towing 10k+ or high profile, mileage was 8+mpg I'd say.
3.73s towed 10-14k lbs flatbed no problem near sea level, but used the whole tachometer unless I was poking around holding up traffic.
I'd absolutely recommend 4.30s for towing duty if you have the choice.
