Honestly a good set of tires would definitely help a lot, and knowing how to drive in mud. My older brother used to have a 2WD chevy blazer, think it was a '97, but he used to mud that sucker through mud puddles that others would probably get stuck in. Dude even used stock tires at stock height, just knows how to drive. I myself have a '99 Xploder 4WD and do the same, technically its an auto 4WD thanks to ford but I've never had to physically engage it. I am looking at tires for that exact reason though, looking at some 32" Falken Wildpeak A/T3W tires, pretty good reviews, especially for mud, rain, and just grip and wear in general(rains so much here...). So I agree, I'd start with some nice A/T tires, work on some other things like the limited slip. I'd also look at lifting it a bit for some ground clearance, I will gladly provide links and advice to help there, researching all that for mine as well! Honestly ya can offroad like ya are (not a fantastic idea at stock but it's too fun not too), just get a winch in case ya get stuck though lol
