I want to install a lunchbox locker, but have read here that locking the front is not a good idea if you drive in snow. Being I live in W.Michigan, that would be me. I have been told by the place where I would like to have this installed, that they don't recommend Aussie or powertrax because they break to easy. I don't intend to go radical off road, just something to get me through where the stock "opens" would loose traction (opposite one front and one rear on ground for example).

I have read a lot of good things about Lokka (Aussie) locker and Powertrax. Do they break or wear out quickly? Has anybody had trouble with them? This will be my daily driver too.
