...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?
Getting back to the op, after 10 AK winters in an open diff truck, and now my 6th in a limited slip diff truck, there are two simple bits of advice. When the back ends starts sliding, get off the gas. If the roads are bad, put it in 4wd. I haven't found any downside with the limited slip, and with a high torque diesel engine I think it's a must as it's very easy to break the back end loose when you're pulling away from a stop.
