The 2wd's are pretty good offroad, no matter what you do. They obviously won't ever have the capabilities that a 4wd has, but with a locker in the back, some 33s+, and a decent lift, you can go quite a few places. Clearance is the biggest thing. If you have the clearance (obv. keep you from getting hung up in many places) you will be able to continue going through whatever it is you're doing. j602 has about 8-9in of lift and 35s, as well as a no-slip locker in the rear. From what I've heard, he can do a pretty good amount with his truck. Same with boominXplorer. He has a Mounty with 10" of lift and 35s and w/ the help of his nice 5.0, he's able to power his way through a lot of stuff. Like I said before, it won't ever have the capabilities of a 4x4, but when it's setup right, it can do a pretty nice amount of stuff.
