Well, the last blizzard we had, I was able to romp through drifts as high as the headlights...and go over the one's taller than the truck...and drive circles around stuck trucks in about 2' - 3' or so.

A lot depends on the quality of the snow, and if you can compress it with your treads to get a bite...or if it walls up in front of you, or ramps up the frame to high center you, etc.

(Powder is the most fun)

So far, with the AT ko's, the X has been unstoppable...I've seen Interco TrXus do amazing as well....etc.
