Um just a couple of things.
you will find that it is almost imposible ( or rediculously expensive and complicated ) to do a GVM upgrade after the vehicle is first registered.
Its all to do withAustralian design rules, vin plates, vehicle compliance and the federal act.
this issue has been very
well canvased on other forums.
There ARE better quality ADR compliant 50mm balls available in Australia with a larger threaded shank......BUT the 3.5 tonne limit still applies to the 50mm ball in Australia.
think on this....a cheap 50mm tow ball will cost you arround $10, a top shelf one will cost you arround $25.
then we make the step up to the 9 tonne rated 3 inch ball......the ball alone costs arround $200
So remember you are dragging arround that 3.5 tonne how many thousand $$ van on a $25 part.
Better have good safety chains eh
As you can see 3.5 tonnes is pushing the limits of what we understand of pasenger car towing.
UM...BTW, I doubt that you will find a pasenger car or a pasenger derived commercial with a towing capacity on a rear mounted hitch over 3.5 tonnes in Australia.
Are we getting the mesage on the scale of this undertaking.
just to push the matter home....a 3.5 tonne van behind a 2.5 tonne pasenger car is a 6 tonne combination.
If that was a rigid vehicle it would require a truck licence to drive it.
I can tell you I would rather drive a fully loaded 6 tonne medium rigid truck, anywhere, any time than a 6 tonne pasenger car bassed combination on the limit of its towing capacity.
