There is a known problem with wobble that happens when flat towing several makes of cars (including my Malibu). When in a turn and you hit a bump it sets off the tow car causing the front tires to wobble back and forth so badly that you think is coach has a serious problem like a flat tire or the rear axle is coming off! Upon investigation, it happens on vehicles that have electric power steering. One time it happened I remembered to check the rear camera and was surprised to how badly the car shook. Some have used a strap or bung cord on the steering wheel to the door post (like a tow truck operator would do) to minimize the problem.
