We hitch up the van and take it to the towbar people to learn how the load levellers work. We arrive on time but soon realise that we’ve left the van keys at home and can’t open the front boot, we look so green. After a quick trip home we return and have our van ball weight checked, it’s 150kg so we will have to purchase stronger load levellers than those that came with the van. We have these fitted, they are large, heavy, expensive ($700 at the time) and cumbersome but as soon as we tow we can feel the difference. There is no sway in the van at all. From a distance it is easy to see that the car and van are both level. It is money well spent.
