fuctifino. I thought most tow balls were rated to 3.5T though. The very fact that it has an approval number means that it's not a cheapocrap one.

And there is very little info on the interweb, I would be happier knowing the rating then thinking it must be okay as it's got a sticker.

Hi Geoff, you can calculate the max. possible towing capacity over the D-Value. As you write it is 12.6 on this tow ball. The D-Value= ((max.Vehicleweight*maxVehicleTowingWeight)/(max.Vehicleweight+maxVehicleTow ingWeight))*9,81

example: your maxVehicleWeight is 2,8 tons your maxVehicleTowingWeight is 3,5 tons the D-value you need is 15,26; if you have only 12.6 its not enough

oooer. never knew that.

hmmm. wonder if any of the hitches here have a D value marked on 'em. is it some physical property, and thus measurable?
