Dragging a Jeep Unlimited around corners

We have towed five different cars over the years and have experienced the situation that you describe with only one of those cars, a 1989 Honda Accord 2-door. For people who have never experienced this, it is difficult to understand. It has to do with the steering geometry on the car being towed, and also with the distance from the front wheels on the car to the tow bar attachment. We finally were able to eliminate this problem with the bungee cord solution mentioned above. We hooked a strong bungee cord to the steering wheel on one side, around the back of the driver's seat to the other side of the steering wheel. This gives the car steering some additional incentive to return to center. If it still continues to happen, a tighter bungee cord may help. I feel your pain in trying to explain this phenomenon, people assume there's something wrong with the way you're doing things, and in reality, it's not your fault. Good luck and hope this solves your problem.
