...for those with a lot of slick highway driving experience with one...
I know they'll get you going and keep you going, but how are they for icy highways? Will it break both rear wheels free and skid you more than an open diff? Can they be more of a liability than an asset on ice?
The only problem I've had on the highway in ice and snow is when the automatic trans decides to downshift going up a snowy hill. That nearly caused me to end up in both of the ditches once. Locking out the overdrive prevents the problem.
