I'm not so sure yet. I already have a truck so hauling space isnt a huge deal but still having more space is better than less so its really down to how the overall package is to decide on a 2 vs 4.
Tell that to the thousands of bone stock Wranglers that never see more offroad than hitting the curb at the local Target parking lot. Sure the hard-core fans provide a brand image but they are definately not keeping the whole thing afloat.
