Sorry for late reply Chris, I have been away! I do not know the ball of the big trailer as we loaded it in a different way every time. We always were empathetic to the drag on the ball so I am guessing we never exceeded the 200kg! I drove it back from Brisbane to Sydney one night and honestly forgot it was there............I put my foot on the brake and nearly had an accident in my pants when this huge white thing appeared in the brake light reflection in my mirror! Damn Range Rovers.........so good they are almost dangerous!
