dingy towing 2017 Jeep Cherokee Latitude

I purchased a new 2014 Latitude and towed it with my Super C. It did the death wobble on me. At the time Chrysler said nothing was wrong. This happened to me three different times, miles from home. It made the whole rv shake and when I looked in the rear camera, I thought the Jeep would tear away from the hitch. My wife said we were not going thru that again. Traded it in on a Grand Cherokee like I had before. Now they have discovered the electronic power steering was the problem. Thus the need for the special power cord.
