I have a stock 2WD, and I've been pretty surprised by it's capabilities. I've gone up some pretty steep slopes, through fairly thick mud, and a pond or two. I've gotten it stuck once, but I always go with another vehicle behind me to pull it out. My best advice is to get out there, be careful with it, and see what you can do. Don't go crazy, and have fun. ScottXGTR is right though, it's going to make you wish you had a 4x4.
