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.

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 ?
