Thanks, I am always trying to compare to what I have. I think 3E is 3.73 locker.

I got the truck used (with less than 10K miles) so I’m not really sure about the axle. I have been looking for the 3E code but I haven’t found it. Do you have a reference?

My truck has the 3E code on the door sticker. My window sticker said it is a 373 E Locker option. 373 was standard in the 2017 models. I also have this tag on the rear end.

But to add a semi-data point to the thread. On the trip to Alaska, my lie-o-meter has me at about 11.1 pulling my trailer weighing about 8k.

As for gears, I use all 10. Hahaha

3.31 I figured with over half a foot-ton of torque I could go for mileage. I've had no problem pulling up steep grades with the trailer.
