What transfer case does it have? I havent ever heard of a jeep that could not be flat towed. I'm not positive on jeeps, but my Scout is towed; trans in high gear, T-case in neutral, hubs unlocked. That would be for the D-18, D-20, and the 300. Now if you are Quadra-trac, I dont know anything about it. To know for sure you need to find an origanal owners manual. The information you seek would be in there.
