I have a 2011 2500 Suburban too. While it has done everything I ask of it, there is no reason to change out your current Yukon Denali. We have only been through the Application mountains, but no problems maintaining 60mph if I wanted in 3rd gear on any inerstate. The 2008+ only comes with 6-spd (same ratios as yours) and 3.73 axle. 4.10 is HD pickup only.
I see quite a few reasons to switch:
1. Suburban vs yukon = Tons more cargo room and leg room.
2. 373 vs 342 rear end
3. longer frame, heavier frame, bigger brakes.
4. 6L90 trans vs 6L80
5. An engine that is proven and built for heavy duty application(6.0)
6. We live in the sticks on gravel road and I think over time the burb 2500 will hold up better to the abuse.
7. The ability to trade up on a bigger TT without worry if the tow vehicle can handle it or not.
8. 9,400lb towing capacity vs 7,900lb
9. Last but not least is peace of mind. Knowing that what you are towing with is specifically designed and built to do what you are doing with it.
