Caravan check point

As the owner of a weighbridge I often weigh tugs and vans. The worst was a new bogie van behind a prado that had 390 kgs on the ball and was empty except for water and gas. He could only put 90 K's in the van before the legal weights were exceeded. He went back to the manufacturer who then blamed our weighbridge, he persisted and some remedial work was carried out but he had to buy another vehicle that could tow the van. In my opinion from all my weighing the system is corrupt and as an owner of trucks and subject to the chain of responsibility rules it is discussing that they can get away with it.
