Best diff option for slippery mud roads.

[jumpsoffrock]

Sometimes I think folks get a little caught up in modding their vehicles with things that aren't necessary for their way of life, but because it sounds cool and other Hi performance cars have them.

I don't go offroad nor do I race.
I am rebuilding a 1-ton SRW truck to use as a work truck. I have found myself in a few muddy situations in life, only getting stuck twice.

What kind of differential would do me best? Detroit locker? Tru Trak?
Will neither of those do any good on muddy roads? Or slippery dusty dirt roads?


Thanks for any thoughts.
