With my too tall 3:42 gears I am about the same RPM in 5th as if I had 4:10's in 6th.
I am comfortable towing at 62 in 5th or even 75 in 5th so the 4:10's will be great in the 15 I have on order.
In pic I was bucking a head wind Westbound on I-40 across the Texas Panhandle towing a 29K combined load. When I have 4:10's the picture will be about the same only 6th gear will be selected.
You'll get better mpg also with the DEF...I've got a little over 26,300 miles on my truck with only issue being to replace a windshield washer fluid pump.....Running flat land, you'll see a difference that will leave a really stupid grin on your face Ron:) Towing in the mountains, you may have a maniacal smile on your face that may scare others around you:B
