May be these could help me sort out my dilemma.Can anyone explain in detail what these mean.When we orderd the Coromal we advised the manufacturer that the towing capacity of our old car (now sold and have a newer one with double the towing capacity) was only 1400kg so we needed to keep the weight down. It arrived with the plaque attached with the following figures. ATM = 1420,GTM = 1321,TARE = 1124 and Axel Group Load Capacity = 1700.We had the van weighed on a weigh bridge with only a few items in it (approx 45kg) and it was spot on 1400kg !!!!! So is the van nearly at its max weight ? I can accept that the awnings and fridge and other factory fittings will add weight but surely we should be able to put a few hundred kg into it and not have to worry about being over the limit. Any help would be really appreciated.

Some clear explanations regarding ATM etc LINK . Some manufacturers are less than accurate with weights they claim their van weighs and exactly what they can carry. Some have been know to be at their maximum once the water tanks were filled. Have you consulted the van manufacturer or distributer for an explanation?

Hi JC,
My Rodeo has the following Tare 1800kg, Agg 2900kg, GCM 4900kg.
In WA it means the max vehicle plus trailor cannot excede 4900kg with brakes.
therefore if I load the vehicle to the max of 2900kg legally I can only tow 2000kg even though it is licenced to tow 2500kg with brakes. If I have to tow the 2500kg I have to remove 500kg off my trayback.
Remember all states are different.

The states are the SAME with regards to what's applicable to what weight can be put where if written on the compliance plate, if there is NO GCM stated, the state's guidelines do vary

The link supplied by DIO has detailed explanation for GTM, ATM, etc.
The tare is what it SHUOLD weigh empty, you weight it empty + 45kg and it's at 1400kg, some thing's a miss there.
The axle weight is the maximum allowable weight that's applicable to THAT axle, NOT the chassis of the van

I'll have a go

Tare is the DRY weight of the van no gas no water.

ATM is the maximum loaded weight on all wheels and the jockey wheel

GTM is the weight on the AXLES only as in when it is hooked up to the car.

The difference theoretically can be the ball weight.

HOWEVER it will vary depending on how you load the thing.

AXle Group capacity is the maximum weight allowable on the axles and should be 120% of GTM

A single axle van SHOULD have a 300kg difference between Tare and ATM

The ATM should be less than the rated capacity of your vehicle.

The BAll weight forms part of the vehicles payload so if you have a vehicle

with a 620 kg payload allowance and a ball weight of 220kg you can only put

400kg of gear including fuel and yourselves .

I would seriously query the figures as our Coromal is spot on for thr weights on the plate.

Thanks Graham,the figures you have posted seem to correspond with the plate attached to the van.The difference between the ATM and Tare is approx 300kg (give or take 4kg).It just seems that we can put very little into the van due to the factory fitted equipment.Would the Tare weight of the van have been weighed after the factory fitments or before ?

Many thanks for the quick replys.I have had a look at the supplied link and it does make more sense.What i will do soon is take everything out of the van as it was when we purchased it and then take it over the weigh bridge.At least then we will know exactly what we can put in it.

All of the appliances such as the fridge if its a fitted one and not a portable and gas bottles, empty, are normally included

Awnings may or may not be depending on what was ordered.

The Tare Weight should be the weight of the van when it left the factory and may include gas in cylinders (upgraded VSB1 specs) but with water tanks empty. Any items fitted by the dealer will eat into your load allowance of 300kg. If things like an awning and battery etc were fitted by the dealer then go back and ask that an updated compliance plate be fitted.
