110 towing capacity - no where near 3500kg
As an example of how far out the 10% rule can be - we just purchased 10 new trailers to put generators on. 8 of them 2,700Kg GTM and the other 2 are 3,500Kg GTM units. The manufacturer has stated a tow ball weight of between 4 and 5% for all of these and in big bold type ‘MUST NOT EXCEED 8%’
They are constantly battling the 10% myth and it drives their Rep mad.
We’ve ended up with around 5% on the 2,700Kg units (total weight is 2,380Kg in these) and 6% on the bigger units (that total 2,940Kg)
They all tow beautifully - mind you, I wouldn’t want to tow the big ones very far with any normal 4WD - 3,000Kg is a bit beyond them even if it is technically legal.
Weight distribution is far more important than tow ball weight.
