We have around 8-12 inches of snow on the ground right now, and I nearly got stuck in it with my family on Thursday (had to stop on a steep hill, had a hard time getting any wheelspin to get going again, ended up sliding sideways into the ditch slowly, before backing out in 4-Lo).
So today I drove down ~20 miles of snow covered Forest Service road to figure out how to drive the GX in the snow. I found that 4-Lo sucks in the snow. A-Trac seems to kill throttle with any amount of wheelspin and kept the tires from digging down through the snow to the ground. In 4-Hi, stopped on a snow covered-hill, with the center diff locked and VSC off, I'd initially get some slow wheelspin after which traction control would start to kick in. When that happened I'd punch the throttle, the brakes would clamp down on the loose(r) tires, the engine would easily rev to 3-4k RPM with tires spinning, and I could dig myself out in around 3-4 seconds with no problem. Traction control AND wheelspin proved to be a great combo, and made the GX unstoppable. Not sure why wheelspin seems to be limited in 4-Lo (maybe to keep from breaking driveline parts?), but at least it's allowed in 4-Hi.
