You need to do the maths on rear axle loading as the additional loading will be roughly twice the weight of the scooter and towbar..Contact PWS towbars.
In this case I would say something was wrong. My Swift sinks around 5mm at the rear wheel arch when I load my 98kg scooter and handing is not really affected, not that it has much in the first place. I have no extra assitance on the rear springs.boyo1414 said:I took the chassis extension tow-bar off my Hymer 544 ,,,,,,,,,and the van leapt up into the air in relief,,,,, and it drives much better without. The van is fitted with air assisters on the rear springs.
After the removal it was obvious that the extra weight had made the van wallow around corners and sway to an alarming degree,,,, goodness knows what it would have been like with a scooter on board as well.
Be aware that your van will drive differently with the extra weight
