The rule of thumb is that the noseweight should not be any more than 7% of the weight of the trailer caravan, either laden or unladen.
When Laden, the other sensible guide is that Noseweight should always be a minimum of 75kg for stability
and should NEVER Exceed 160kg under any circumstances,100kg is seen as optimal.
Some Southern Hemisphere Manufacturers have chosen to ignore the consequences of super-heavy noseweights. 300kg is actually dangerous and ridiculous in operation on the wrong car.
WE have checked with Nissan and Mitsubishi to-day and their aftermarket Dealer supplied towbars are rated to a maximum 120kg.
And so is the potential 'Tow car of the Year', the Audi Q7 V12. The maximum load weight on the nose is 140kg, in Tare weight, and fully
laden weight. So with 1000 Newton Meters of torque on tap, this World's best tow car can't possibly tow most of the units on offer in
NZ.
Towbars are rarely designed for any excess over that load and could well invalidate the warranty on the towbar unit and/or towcar.
Please check with the suppplying dealer or manufacturer. Even better wind all the
legs up and see whether you can physically lift the front of the caravan.
Also consider that the combined trainweight of the complete towing outfit. ie Car and Caravan combined cannot exceed 4500kg unless
you get a HT Licence, and have both units COF'd every 6 months.
If you are unfortunate enough to have an accident whilst towing a caravan car combination of a combined gross weight of over 4500kg
you are unlikely to be covered on your insurance and liable for prosecution by the Police.
One manufacturer here refuses to publish any ex-works or Maximum Permissable weights, or personal load factors.
Even more worrying is the complete lack of Downforce Noseweight technical data.
They cite that every unit is bespoke and individual? So are, all ours when they are despatched.
All components can be weighed, and as a minimum requirement they should issue an accurate weighbridge ticket with each
unit delivered. Also one for the downforce weight on the tow ball.
Just what exactly are they trying to hide?
