If you have the lower gear you won't need to put your foot to the floor! :R And as you know, all vehicles have torque management systems within the ECM so if you put your foot to the floor it will de-fuel the engine to protect the drive-train. But if someone wants to beat their $56,000+ vehicle I guess you would have a valid point maybe.

4X4 I'm not arguing for the 4:10, just making a point that the 4:10 will tow it better then the 3:42. Just like a big block will tow better then a small block or diesel over gas. Can the 3:42 tow his trailer, yes. Will the 4:10 tow it better yes it will. The question becomes does he want that extra security, that's all.

When going down the road in high gear at 60 mph the 4.10 axle will allow the truck to run in 6th gear at 1630 rpm. If he gets the 3.42 rear axle and finds that he doesn't want the truck to run at 1360 rpm he can lock out 6th, have the truck drop to 5th and run at 1660 rpm. This way the power won't be sped up as much in the transmission only to be slowed more in the rear end. When he is touring around empty he can use his second overdrive. (my guess is he will use his second overdrive even when towing under many circumstances).

That is how I tow. 6th in normal conditions 5th when it's hilly or head winds. I would say for me the biggest reason to get the 4:10's would be starting off on steeper hills. Other than that I use the gears, that is why I say I am happy with the performance even tho I have the 3:42 gears.

I guess I would have to think long and hard about what gears I would get.

I don't think they will get much different mileage solo with any of the 3 gears ratios.

Mileage difference is not at all what would sway me one way or another.

Any of the 13's will get better mileage than mine.
