    Do you guys think that a V6 executive is up to towing a car from Melbourne to Sydney?
    Anything thing special I will need to keep a eye on or get done before I do it?

    Dumb question but what are the risks of using a 1200kg towbar tow a 1900k trailer. I don't plan to do it and will get a 2100kg towbar fitted but what would happen if you did do it? Would the bolts get stripped, towbar get warpped or will you just get bad trailer sway?

    You will find that you will need a petrol tanker following you to keep up with high fuel consumption.
    Using a 1600 kg towbar to \carry 1900 kg is illegal. You cannot legally carry/tow more than (a) the ratiing of the towbar (b) the maximum allowable for the car (whichever is higher). I guarantee that you would not only cause damage to the rear panels of the car but as suggested, most likely sheer securing bolts etc. Nice thing to happen across the Nullaboor etc.
    As for 'trailer sway' it will depend on the configuraton of the trailer, single or dual axle, the length of the draw bar, the diameter of the trailer wheels, the ball weight when attached to the car (this should be less then 10% of A.T.M) Aggregate Total Mass (combined weight of trailer and load). For example, if the combined weight is 1900 kg then the ball weight should be lees than 190 kg
    It is also very likely that you will require WDH (Weight Distribution Hitch). Once the trailer is attached the back of the car will drop resulting in a lessening of steering capability. Such sitiuation can cause serious trailer sway (can result in total loss of control and roll-over) and because of less weight on the front wheels, the steering will be much lighter and the vehicle may also become increasingly difficult to control (especially in wndy conditions).
    I would also suggest that you carry several spare tyre for the trailer and make sure that the tyres on the towing vehicle are in very good (perfect) condition. Owing to the heavy weights involved ,sutained towing/travelling and additional heat generated, tyre failure are very likely.


    If you need more serious reasons in regard to the complexity of towing without the correct tow vehicle, trailer and towing aids, let me know and I can provide all you want.



    SPEED LIMIT

    (S)

    Since December 1998 all trailers can be towed at the speed limit for that particular road with the exception of Western Australia.



    You should remember that in some cases motor vehicle manufacturers place speed restrictions on a vehicle when towing over a certain mass. Ford only permits 100km/h if the load is less than 1200 kg. At 1600 kg this drops to 90km/h. The speed further reduces until at 2300 kg, 80km/h is the maximum. Holden takes a similar approach but also ties the vehicle speed to the type of towing equipment fitted. Spending a few minutes reading the trailer towing section in the owners manual is highly recommended.





    In 1989 Australian Design Rules (ADRs) were introduced which affect the construction and towing of trailers, including caravans. Currently there are no towing regulations which specifically refer to ‘caravans’. The ADRs include the requirement for plates on trailer drawbars which amongst other information states the aggregate, or maximum, mass of the trailer and data on the towbar which indicates the rating of that towbar. It should be noted that ADR 62 states that the rated capacity of the towbar …. “shall not exceed the vehicle manufacturer’s recommendations”. Below is a summary of the rules relating to towing weights which should assist in the selection of towing equipment and/or caravan and the towing speeds applicable to various states.



    While there are some variations in the Road Traffic Regulations in different States, most agree on the following safety aspects:




    The trailer must not be bigger or heavier than the driver can safely control,




    The total or laden mass of the trailer must not be more than:

    - the maximum mass (A.T.M.) determined by the trailer manufacturer and as stated on the trailer plate,

    - the load rating of the trailer’s coupling of the towbar fitted to the towing vehicle,

    - the total load rating of all the trailer’s tyres.




    The combination of tow vehicle and trailer must be “properly set up”. This means that there is a load of about 10% of the total trailer mass on the towbar and that the outfit has a level attitude. Generally this necessitates the use of a load distributing device.




    Exceeding the maximum towing load as recommended by the towing vehicle manufacturer can:

    * Invalidate warranty

    * Nulify insurance, and

    * Effect long term vehicle safety and reliability.




    The new towing regulations allow the owner of a 4WD, ute or car to tow a trailer weighing up to the vehicle maker's recommended maximum.




    Unbraked trailers with an all-up weight under 750kg are approved under the new uniform law, but trailers weighing more then 750 kg must be fitted with brakes.




    The changes are a result of uniform vehicle standards proposed by the National Road Transport Commission and approved by Federal Parliament.



    The only exception to this is in Western Australia where the maximum speed limit is 100km/h for vehicles towing a trailer with an ATM of over 750kgs

    Pay a freight company to ship for you, it will be less hassle and less ware and tear on your car, google companies who move cars state to state
