For those it interests::: We took off a couple months ago and hit primarily the Colorado, Wyoming, Montana, N Dakota ... mostly Rockies. Dropped the 265 stock tires (they sucked) and installed...

Not bad for MPG on a gas truck and heavy camper.
My 09 D/A doesn't do much better for MPG.
Seems like good mileage but as asked above, bet it's at slow speeds. Set the cruise at 75 and watch the needle drop!
Grit Dog -- yeah, probably so. But I usually run at 60-65 on highways and slower on back roads. We go on these trips to enjoy the back road scenery and wildlife, not to run as fast as we can to "someplace" so it's fine for us to see where we're going as we go, not to look in the mirror at something we missed.
At 75 mph, it takes more to control the truck safely too - so, why do it and struggle. Yeah, I know, some need to speed due to time constraints, but if you can't enjoy the ride, why bother?
We're pretty happy with the performance all in all. Like the six-speed vs the four-speed we had in the 2003 6.0L w/3:73 -- and the 4:10 gives the power without losing the mpg. I'm guessing the 3:73 would gain in mpg w/6.0L, but lose muscle in the hills. This is a very good combo. We were hoping to get 10 mpg - so, nearly 10.8 is a nice surprise.
Couldn't agree more. We travel even slower, 90-95 kmh. With our combo it is routine to get 16 US mpg all day long. Just saying....
The wind resistance is the killer. On flat ground I am at like 10lbs boost and 800deg egt at 55-60 mph in 6th. At 70-75mph that's 20-25psi boost and 1000+deg egt.
Not sure how you can travel slower when goin x country or driving in the middle of nowhere plains of fields. No one goes 55mph on the freeway. Take 2 days to cross Nebraska lol!
