I honestly don't know the difference between lockers, and limited slip, factory options, etc. that is why I am asking the pros.
I know is my '00 silverado has a factory "locker" and in 2wd there is no comparison to how much better it is than my van. And my van has thousands of lbs of tools that my truck doesn't.
Living in MN for 40 years, I have done my share of driving in crappy conditions. I just don't like getting stuck at stop signs on plowed roads, or not being able to climb my almost flat driveway with a tiny bit of snow on it. I really just want something that gives me a little extra traction when I need it.
I appreciate all the help so far.
