LOVE this 8.1 Burb!!!
Well just got done with a 1500 mile road trip pulling a 39'(with cargo rack) TT loaded to at least 9K lbs. This is the first real trip with the combo. It performed great. I was telling my wife how ...

To each their own. While not as stable of a tow vehicle, I’ll take the drivetrain of my 2011 Yukon’ XL Denali over the previous 2003 Burb 2500/8.1. The Yukon pulls with much less effort and faster speed over the passes than my Burb could.
Hmmm. This is just odd to me. I pulled the same trailer with both the 6.2 and the 8.1. I broke one 6.2 and replaced it with a new GM certified 6.2 installed by GM and it still struggled. It overheated and had to stay way up on RPM's to move the 5k trailer. 4th gear is all it could ever get to.
I traded that in for an 05 8.1 and towed the same trailer on the same trip with the same temps. The burb towed it in 4th gear 95% of the time. It only hit 3rd gear on the long steep mountain passes. I couldn't even imaging trying to set my 9k lbs trailer on the back of that denali.
I guess it all depends on what you are towing and where. Maybe sea level affects the big block more than the 6.2. Don't know?
