Why 4.1 axle?
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...

Scooby,
Yes your overall low of 36-1 example of a 3 @ 12-1 setup will have more stress on given components than any of my 4 examples totaling 24.x-1. Yes 36-1 will get a given load moving easier, up a steeper grade etc. My 10.08 trans with 4.33s in my Navistar will get things moving easier than any of yours or my examples. The OP does not have these options.
I did give the two final drive ratios for the 3.73 @ 4.10 option the OP is looking at, either will not stress his setup. One barely meets grade I mentioned, the other will. If he only need to pull a 25% grade, both will do so with cushion!
At the end of the day, what will or will not work for your needs is what one should pick from a drive train standpoint.

Ok, you want to keep the overall ratio at 24-1. Let's use a 6-1 trans, 4-1 rear compared to 8-1 trans 3-1 rear and 12-1 trans and 2-1 rear. All will take the same engine torque, and multiply it by the same amount. But if say the drive shaft turning the 4-1 rearend is handling all the torque it can, but moving the load, change to the 2-1 it will break. But if you instead change the trans, and keep the 4-1 rear there will be no more strain on the shaft, because the load moves
