I agree with mbeach on the limited value of the VX's TOD system on snow. It kind of works, of course, but I hate the way it kicks in full 4WD for all of a couple tenths of a second, then it's right back to 2WD. When accelerating from a stop on a snow-covered road, it makes for a jerky, skidding run. I'd be happier if it stayed in full 4WD for a few seconds after kicking in, even. I will hopefully do the select-a-TOD-mode modification to the TOD computer wiring before this winter - it will allow me to get the system to stay in 4-High when I want it to. That's how I want to drive on a snow-covered road... in full 4WD-High.

But while I dislike the TOD system's dynamics on snow, I quite like the way it works on dirt and gravel roads. There's a fun one near where I live that I can absolutely FLY down like a pro rally driver with the TOD system doing its thing perfectly.
