I, too have experienced this rocking problem. After towing the Jeep initially symptom free for 8,000 miles, I had this happen. The Jeep goes out of control, rocking the MH back and forth. This has happened three times under different circumstances. It happens with different brands of motor homes, different chassis (front gas or diesel pusher), different tow bar systems, different braking systems. The only constant seems to be that they are towing Jeep Cherokees. I have logged a complaint with the U.S. D.O.T. I encourage others who have experienced this to do the same.
