I haven't palyed around too much in trails or the snow, I don' t go alone If I go I go with my brother & his 1/2 ton chev & his quad. I don't plan on rock crawling or anything, I use this for daily driving too. Moab & stuff like that would be cool but It wouldn't be in my daily driver
That being the case, you need to weigh if a traction device like a locker or a limited slip is worth the investment. I would definately think a limited slip would be a better choice for a daily driver that sees only light trails if you decide to get one, but they will be more expensive than the lunchbox type lockers Bounty Hunter mentioned (installation cost would be higher, not necessarily the unit itself).
What kind of tires are you running? I would address that before even considering a traction device if you have street tires. Even some all terrain tires can make a difference over... say... stock Goodyear GSA's. Even better, many of the newer mud terrain tires wear alot better and are quiter than in the past and the difference will be night and day. If you already have good tread and want more traction then try a LS. If not, get some good meat under that Jeep and go from there.
