Gooday,
can tell you 2 methods. First ring nearest Dealer & see if they have a set of Ball Weight Scales & if they will do it, & how much $. You unhitch & place ball on scales.

2 Go to a Registerd Weighbridge with Caravan in tow, drive on so towing vehicle is off bridge but caravan wheels aren't, they note the weight. Then reverse enough so the caravan wheels are still on, unhitch caravan, insert Jockey wheel making sure that is also on the bridge & get them to note that. Difference between the two readings will give you the Ball weight on your tow vehicle.
Hitch up & drive home with the Certicficate they will give you. Will possibly be a fee too.
Cheers Boroma604.

Here's a few sites that might help you figure it out:

Caravan & Camping SA
Harding Caravans Services

The following should also give you some idea of the aspects of weight and distribution on the towball/towbar system:

The only way you could get these figures would be to take the van to a weighbridge. You need to weigh the van on the bridge without the car. In other words with the van wheels and jockey wheel on the bridge and then weigh it again with just the van wheels on the bridge. Doesn't matter if the van is on the car or jockey at that stage as long as only the van wheels are on the bridge.

If you subtract the weight on just the wheels of the van from the total weight including that on the jockey wheel you will then have the ball load.

Should say what state your in , if in NT ie Tennant Creek or Katherine you could zip down the W/B and do it yourself if the Inspectors are not there,

if you go to the haymen reese site they have a load of info there including setting up your household scales without stuffing them while doing the weighing
