Like the others have said, a well-built 2wd with a locker and good tires will take you just about anywhere a 4x4 will go. The only thing it really can't do as well is climb rocks and stuff. But trails, mud, etc, it'll do just fine, and there's less stuff up front to break on ya. One thing I will say though, if it's a dodge ram 2wd you're looking to lift, watch the front wheel bearings on the 1500's. They suck. Dodge used the exact same wheel bearings for the fronts as those found in a Ford Tempo. Sad but true. So if you decide to run a 37" swamper on a 10" wide wheel, plan on chewing up a set every few months.
