3.31 gears at 40,000 lbs gross.
Just to give a bit of a feel for how different gear ratios would behave while towing I locked out 10 then 10th and 9th then added them back again while travelling on a straight stretch of road w...

Yes but the engine and trans are working harder in each of the gears with wrong gearing!
No, they are not. They are working the same. Same input engine RPM. Same output wheel RPM. How it gets from A to B does not matter.
What does matter is having 9 and 10 available when NOT TOWING for efficient cruising.
You guys who are still adamant that 3 gears are plenty, are complaining about using "only 8?"
You have to understand physics and how the transmission and rear end gearing work with each other. It’s more than just running the trans one gear lower.
Share the physics for us. I'm an engineer so you can use big words.
At best you may come up with a percent or two difference in efficiency but without a detailed analysis of all the loses, could say if that difference is positive or negative...but running light, it's well established that a lower numerical rear end is more efficient.
