New to this forum, so "hello" and thank you for all your inputs. Regarding the 2014/2015 Jeep Cherokee wobble behind the motorhome, I, too, have experienced this on three different occasions. In searching for answers, I have found more than 20 other owners who also have experienced this problem. They drive different motor coaches, use different brands of tow equipment. The Cherokee is the common denominator. It is very dangerous when it occurs and will not cease unless the rig is brought to a complete stop, which, as you know, is extremely dangerous on highways with traffic. Individual owners have tried many various fixes, most of which were mentioned in this thread, but to no avail. This is a real problem. One owner had his wife drive behind him and use her cell phone to record the wobble. We have posted complaints with the NTSB. Chrysler won't acknowledge the problem because the dealers can't duplicate the issue. The video clearly solves that problem. For those of you have this model Cherokee and have not experienced this wobble, if it happens to you bring the vehicle to a complete stop as fast and safely as possible. Slowing down will not eliminate the wobble. For those of you thinking about buying a new/used Cherokee to flat tow, I suggest you watch the video before making a decision to purchase. This problem has surfaced on vehicles with little lmileage to those with more than 15,000 miles.
If it's possible to post a video here, I would be glad to upload it. The owner posted it on You Tube. Just go there and search "Jeep Flat Tow."
