rear locker, should i get one?

[boatpuller]

iv'e got the rear locker in my 08.i really only tried in snow.i slid off the road,and wasn't really impressed with it getting me out of the ditch.but,nothing really would of helped when you go sideway's.however were talking 26 inches of snow.i have a very steep driveway and found it really useful to backup the hill in snow.it worked great.in snow on hills,a head of steam sometimes is the best ticket,so the locker isn't much help.but i think the front and rear would really be cool in the mud or slow speed 4 x ing.iv'e driven 4x4's in snow and mud for 25 yrs and all in all the h3 is the best iv'e had without chains.
