Flat towing is so fast and easy compared to a trailer. Like Reddog said, you gotta do SOMETHING with the trailer once you arrive at your destination. A lot more work to unload the jeep, park and unhook the trailer, etc.
With my folding tow bar, I just unhitch, fold away and off I go. The folding hitch also makes hooking back up very easy as each arm is telescopic. You only have to be close to adjust the arms to put over the hitch ball. AS you pull away, the arms extend and lock into their full length.
