Lol.I pulled a car out of a snow bank a couple of years ago when I had my S-15 Jimmy.Felt good to help somebody out.The funny part was it was a guy that I had repossessed half of his house when I worked for a rent to own company lol.

About the OP,I have no experience with lockers but I would think if your vehicle is a dd wouldn't it be better to have a manually selectable locker?Is there such a thing?

 

there is manual lockers. altho soft lockers are fine on the street

 

just let off the gas around corners and you will be fine. Its just when you have an auto locker and apply torque to the axle that it locks up which in turn causes you to loose traction on ice. In the snow though lockers are way better especially off road.

 

I dont off road really but I think I would not mind a manual locker just for the winter months in case of getting stuck or for the need of a bit of extra bite when needed.
I mean with the manual ones you can be sure that it will not engage while you are doing your daily driving but engage it when needed, seems like the best of both worlds to me personally .
