To add to the discussion remember the difference between ATM & GTM.
Ball weight of around 10% of ATM is generally ok. ATM is the total weight of the trailer/caravan including the whats on the ball. GTM is only the weight on the trailer/caravan wheels.
So if you had a van that weighed 2200kg unhooked from the vehilce with on its jockey wheel & wheels on the weighbridge this would be the ATM, then then you hook it onto the tow ball and weigh it with only the van wheels on the weighbridge this is the GTM so if there was 220 (10%) on the tow ball then 1980kg would be the GTM.
So 10% of ATM is 220kg whereas 10% of GTM is 198kg.
