I went a lot of places in the snow in 2wd without a problem. The rear locker has made such a difference offroad in general. Id offer to let you borrow my tires for a comparison, but i think the distance is a little much!

I was thinking about this and I have to clear the tires partially of blame.
In road snow I can understand why the traction increase isn't as dramatic. On level flat ground the two rear tires have a similar amount of traction. An open diff distributes the torque evenly between the tires in this situation. To break traction, both tires are nearing the limits of adhesion (grip). With an open diff, one of the tires is going to break traction if torque increases. Your already using up almost all your two tire's grip while open. With a locker, you maybe get an extra couple foot pounds of torque from the tire that didn't slip, but because it was already nearly using up all its grip, the locker doesn't help much.
Obviously, if one tire is on ice and the other on gravel, the locker will help where the open diff is stuck, but where the tires have a similar amount of traction, it doesn't do much good.
