Should I weigh my Vehicle, Trailer or Caravan

Not knowing your actual weights is not an excuse, so "Yes", you should have your vehicle and Trailer/Caravan weighed to ensure your tow set up is within the weight limits, is balanced and is safe. 

Statics show one of the leading causes of caravan related accidents is due to overweight trailers/caravans, or caravans that have the incorrect weight distribution.

The other good reason to ensure you are within your weight limits is the savings. There are large fines more than $500 and loss of demerit points if you are caught with an overweight Vehicle, Trailer or Caravan.

Weighboss can weight your vehicle, Trailer or Caravan to give you a full report on all the different weights and where the weight is located, giving you full understanding of current weights and balance. 

Armed with this information you will know if you are safe and legal or what changes will need to be made to your set up to make it safe and legal.


What are all the terms for weights??

GVM:  is gross vehicle mass. This is the maximum your car weigh, including passengers, and payload, your tow ball is calculated into this weight. This is set by the manufacturer and is illegal to exceed.

Tare Weight: This is the mass of your caravan or vehicle with nothing in it. The correct weight is determined by manufacturer’s specifications.

Kerb Weight: Is the weight determined by the manufacturer’s specification, but it will include fuel and coolant in your Vehicle.

ATM: is aggregate trailer mass - This rating the maximum weight your trailer/caravan can weight and is set by the manufacturer and it is against the law if you exceed it.

GTM:  is gross trailer mass and is the same as above for your caravan. It does not include the portion of the weight which will be supported by the tow bar or the jockey wheel.

TBM: is tow ball mass which is exerted on the tow ball once your caravan is hitched to your vehicle.

GCM: Is the combined maximum gross mass of your Caravan and your vehicle it should be between 10 to 15% of your GTM. Too heavy and it affects your steering, too light increasing trailer or caravan sway.

Payload Allowance: Is the difference of your GVM Stated by Manufacture and what your vehicle weighs. The more accessories affect this allowance so knowing what your vehicle weighs rather than the stated kerb weight from the manufacture, gives you a more accurate measurement of your payload allowance.
