All Wheel Drive
Anybody notice any major differences or concerns with 4x4 towing vs All Wheel Drive towing? Considering a Denali with AWD and the 6 liter.

My 2015 Yukon Denali has 2wd-auto-4wd-4wdLo. It works exactly as my 05 1500 did in that in auto when the rear spins it locks the tcase up. In my 05 there was a pretty good delay before that lockup.
