IMO you dont even have to pack lightly with a 2 door. I have a TJ which i think is even smaller than a JK? Anyway I have been camping solo and with a second person. I fit: 2 jerry cans, big tent, two stretchers, two deck chairs, two inflatable mattresses, a table, stove, two sleeping bags and an esky in the back. It was piled pretty high but it fit. With some smaller gear and without the stretchers plus the jerry cans out the back there would be plenty of room for two of you with gear.
