2002 Dodge 1500 Quad 4X4

I am considering the purchase of a 3023 TM. My TV is a 2002 Dodge 1500 Quad Cab Short Bed 4X4 with the small (4.7L) V-8 and I have changed the differentials from 3.55 to 4.10. I live on the west coast and most driving will be in the Rockies, Sierras, or the Cascades - so lots of mountains. Looking for opinions on the combination of my truck and the 3023. If forced to could go down to a 2720 but really prefer the larger size for comfort. And it is a forgone conclusion that I will use a WDH or WEH.
