I wheel in the pine barrens mostly mud & water I crawl once in awhile.
Nice to see a new face here from Jersey.
I havent been to the pines for a long time. But i do have some suggestions for you.
Being there and done that in the pines. My 30 held up fine with 33 in swampers. My 30 took a noise dive as soon as i started twisting the old CJ up in the local sand pits. Then i found rocks and i new the 30 was a goner. Saying that, all i could break were the joints. You jeep has the larger joints.
If you run a not to aggresive 33in. tire the 30 will probably hold up just fine for what you do. It can still break but probably not in the pines, there is a better chance in the rocks, of course, but with a tire that is not aggresive that will give it a good fighting chance.. I ran a lockrite in my 30 in the pines and never had a problem. I found the offcamber twisty stuff and it broke just about right away. Took the locker back out, and it was fine. Once i found the rocks though, a 44 was built and installed. I also run the smallest tire with the group i used to wheel with. So i had to hammer hard some times to keep with the bigger boys.
I wheeled with plenty of guys/girls in the pines and most ran a 30 without a problem.
As for which locker go with, a gear driven posi is the way to go if you dont want to fork down the money for a selectable and still thinking in the future to swicth to a 44.
As for snow, it will of course want to pull both front tires. So yeh it will want to slide the front out. But its all in the skinny pedal. Hit it hard and it will slide.
