Ok, so I talked to a local shop that installs hitches, etc. They said that Maxda/Ford does not want you towing because the limit of the weight carring capability of the car can easily be exceeded. The owners manual states that you can safely carry up to 1400#s inside of the car (that includes driver passengers, and cargo). If the trailer weight does not exceed the total "AND" if the tongue weight does not exceed about 50 lbs, then you are within the safety limits of the car. The problem arises when you put a hitch on the car and try to tow a 2500# boat or trailer, you are easily exceeding the max cargo weight. The car does not know the difference between towing 1400 lbs and carrying 1400lbs, except that the weight is not directly carried by the cars suspension, the engine, transmission and drive train could care less where the weight is located.(as long as it is within the limits).(idhitit)
