Thanks for your input
It's a bit difficult. I'M dealing with GCM, GVM and then Tow ball weight. So I should check out how many kg's the patrol's GVM is and then load my car before attaching the van.
Then I could take it to the weigh bridge and confirm whether it is under or over the GVM and then I can calculate how much I can or cant load on the towbar.

If my GVM is say 250 kg under the GVM I assume I can have a towball weight of up to 250kg. All good

Then how do I work out whether the weight of the Van I am towing is too heavy or not (Is this when I look at GCM?? Do I add the GVM of my car and the GVM of the van and see if it is within the GCM tolerance??)


After looking at specs I believe the Van is Tare weight of 2850kg Ball weight of about 240kg & ATM of 3500KG
