Towing a car with anything less than a 3/4 ton is like going to a whorehouse without condoms. Sure, you can do it... but just think of the consequenses! redface.gif
If you have a proper towing vehicle rated to carry the load you are dragging, you shouldn't need special hitches or bars. My 3/4 ton with class 4 hitch > any load less than 10,000 pounds. graemlins/thumb.gif
