I tow an 8000 pound trailer with a GMC 2500 with 6.0l engine, 4 speed transmission, and 4.1 axle ratio. I rarely need 3rd gear on the highway; only on steep hills. For my next truck, why not get si...

After having fairly similar vehicles with 3.42, then 4.10, then 3.57: I noticed relatively little performance differences in them. I do not deny that there is a slight mathematical and mechanical advantage and RPM difference, but the message here is that the final drive tends towards hair splitting and fine tuning.
It DOES depend- I was towing near the vehicle's maximum capacities- and we spent a lot of time downshifted with the gas engine at 3000 RPM- I actually MISSED the 3.42 to make that 3000 RPM a little slower...Your experience may vary.
Indeed, new multi-speed transmissions make the choice of the final drive much less critical and even more in the hair-splitting / fine-tuning realm.
