10 deg F, icy cul de sac
traction control off, tow haul on
T-case in 2wd
Doughnut city here we come right? Nope, just power drifts, hid in my garage before the neighbors saw me.

Big surprise coming from my Avalanche, but in retrospect, the Chevy was pretty well suited to doughnuts. 18" less wheelbase, stiffer rear suspension, full locker in 2wd, way more low end torque, and what I would call inverse traction control (torque management.) The computer wouldn't allow the DBW to open the throttle past 40% until 10 mph real wheel speed was reached to protect the transmission. Given a little ice, it was perfect, apply throttle enough so the locker locked, the t/c locked and then bam 40% to 100% fuel as soon as wheelspin hit 10 mph. The big block was just into the meat of torque curve there too

That being said, the PW does great on icy roads, I'm finding just turning traction control and MDS off and then use 4wd when/if required. 2wd got me up my driveway yesterday, L/S did a good job applying torque to both wheels. Quite impressed overall. Yeah, the heated steering wheel and remote start doesn't hurt either! (-5deg F when I left the gym this am, was glad the truck was warm.
