Ice Driving! Which engine layout is best?

I have not read through the entire thread, but the OP question is regarding "Ice driving". I doubt that FWD or RWD are good for ice. When I lived in NJ, icy roads were not uncommon during the winter, especially on mornings following a winter rain.
I had a 71 Scamp, a 76 B200 van, and a 69 GTX at the time, and an 81 Jeep CJ six cylinder, with a 6' plow on it, and my wife had an 81 Olds with FWD. They all sucked on Ice.

Now, in snow, the little FWD Olds was better than all my RWD Mopars. But the Jeep really shines in the snow. The funniest thing was that if you had the plow hanging on it in the lifted position, and no one was in the back seat or there was no other weight back there, it used to unload the rear axle almost completely. I used to have to bolt the hard roof on it to counter the weight of the plow. A half dozen 50 pound sand bags behind the back seat helped a lot, too! lol. But, without the weight, I used to have to keep in in 4 wheel drive if the roads were wet, because the rear tires would spin on wet pavement.
