I'd thought I'd post my experience on ball weights...
I have a disco1 and a Kaymar rear step which has a tow hich. The max ball weight 120kg. All OK till I bought a caravan. It was a Roma dual axel and ATM-GTM was 190kg.
Didn't release possible legal issue until safter the first lap of OZ. Note I had a haymen reece weight distribution hitch and the van towed very well.
I'm paranoid about legal issues with insurance and thought they would look at this if I had to make a claim.
First things first , the car manual. There's a difference in the wording in the UK owner manual which I believe says max ball wieght 250kg, the oz version talks about a recommended max of 150kg. Note it also talks about a Max rear axle loading so you need to take that into account also. I had a lawyer friend read over the relevant sections and his interpretation was yes you can go more than 150Kg just not above the rear axle loading.
Next problem was the tow hitch , if it says 120kg and you load more its illegal. Rang around a few
places and all tow hitches said max ball weight of 150kg.... except ARB the hitch they sell is plated 200kg.
Replaced the KMAR with the old bumper and fitted the ARB hitch.
So in summary hitch now is rated to 200kg and as long as I don't overload rear axle I'm legal.
Note I did actually weight the van and the ball weight empty was more like 280kg , van was empty. There is no way it was ever 190kg when it left the factory. Moved water tanks around , added dual spare wheels, still above 200kg. Van now sold and looking for something new...

That is because Ball Weight never equals ATM - GTM. The ATM & GTM are legal limits and you will rarely see these figures when you place a van on a weigh bridge. When you take delivery of your van the ball weight is the tare weight less the axle weight, it probably will never be the same weight again after you start adding things to your van. The ATM & GTM two figures are legal limits that you are not legally permitted to exceed at any time when you are towing your van. When talking about your van's loading you should be talking about aggregate weight and axle (or trailer weight.)
The ball can only ever equal if you can actually load your van to exactly equal the ATM and GTM figures. However if you do this there will probably be too little ball weight on your tug. Thus if you are concerned with safety I stand by my first sentence.
2nd thing - the maximum permitted ball weight is the LESSER of the manufacturers specification and the specification on the compliance plate on the tow bar. In the first case you were limited by the 120 kg limit on the plate on the tow bar. The current situation is you are limited by Land Rover's 150 kg limit.
