Your best mileage, class A diesel.

For me, on my last big trip, the difference between 55mph(through the mountains) and 70mph(with a head wind on flat terrain) worked out to about 2 miles per gallon.

I also don't really care about mileage. It's interesting to know and makes me want to strive for the better mileage, but it's not what I bought a big coach for in the grand scheme.
Comfort costs money.

Your exactly right. We can't drive our homes down the road and worry about fuel consumption. I get great mileage while in traffic,,,, slow,, no speed,, and my MPG builds,,, as soon as the I can get on the pedal again there goes the MPG. I really don't care about MPG either but I really like to see my "miles to empty" after putting 200 gallons of fuel in to be higher than lower,,, LOL,,, . I have worked with my unit to get a solid 8mpg over the 6mpg I was getting when I started. Sure is nice to see 1600 miles to empty than 1200 miles to empty after I fill up. 400 miles of extra travel for the time and money I spent is well worth it.
