Considering the altitude and percentage of low range driving, now bad mileage. Being happy with what you get is the most important thing.

Didn't climb as high as last trip and averaged 10.1 mpg.
Very pleased at the grades it climbs in 4th gear.

On a good day the best my work truck, an '09 F-450 with the 6.4 got empty was 9.4 mpg.

I think you are comparing apples and oranges. Btw, my ‘10 F450 got better than that stock.

Besides, most people don’t buy a F450 to get mpg just like most people don’t buy a Chevy 6.0 SRW to haul or tow heavy loads.

And where are you getting the mpg data? Not from the truck display I hope.

I’m not sure who you are asking, but most trip computers on my vehicles have been pretty accurate compared to hand calculating.

In any case, mpg can vary a lot by simply using different gearing, going slower, easing into brakes/gasoline, etc.

That's pretty impressive fuel mileage.

My work truck gets 4.5 mpg towing close to 15,000 lbs.

I recorded every gallon of diesel I put into my 2010 Ram. Periodically I calculated mileage and also compared it with the trip data. Fully loaded I got about 12 mpg on the open road and the trip data typically gave me 13 mpg which is an overestimation by about 8%. With mountain driving the overestimation was even bigger.

If you do record miles and gallons used, it can take quite a while to get accurate data. Pumps are different and it is hard to fill us exactly the same each time. I doubt you can get much accuracy trying to calculate based on 88 miles or even twice that for a round trip.
