I've not tested my Van in snow and Ice nearly enough.
Previous RWD and Fwd vehicles I would intentionally throw the ass end out and around to learn how it responded to more or less gas and counter steering in both ice and snow and on gravel/dirt. Driving on ice with little to no traffic, on flatlands was something I greatly looked forward to as I would be drifting sideways well before a turn, and confident in my ability and control with a manual transmission.
The one Time I found a nice car free parking lot covered in ice and snow with my Van(open Diff), I could not get the ass end to swing out without using the parking brake. Usually the inside tire would just spin and hiss, or the front tires would just push, and I imagined an exploded differential if it suddenly grabbed, so I quit testing it and wasting fuel, and as such I have no really practice with how it would respond, and I do not like that.
Now 4 wheel higher speed drifts on Baja's backroads washboard were fairly predictable. I would drive with wheels on the loose stuff outside the regular ruts and just get a feel for the CG of the van, and how to toss it around, but passengers were horrified and screaming which seriously cut into my joy.
Buzzkills.
Since those days I have rebuilt my suspension with thicker front coil springs( moog 7272), and gotten rear helper airsprings and slightly oversize AT tires and KYB gas-a-just shocks on all 4 corners. After using a tape measure on a perfectly flat surface, adjusting Airbag pressure to get equal ride height on all 4 wheels, the van handles surprisingly well. When Descending the near vertical mile in the Sierra's out of King's canyon, I drove like a maniac with a couple 4 wheel tread scrubbing drifts on dry asphalt.
No doubt a passenger would have been screaming again, but I was free of such encumbrances on that thrilling descent.
I smoked a bunch of brake pad life though, and more recently replaced calipers and pads.
