We are new to caravanning, having bought our 2017 Bailey Pegasus Genoa 4 just a few weeks ago. Our tow car is a VW Tiguan 2.0 diesel. The target nose weight according to Towsafe is between 63 to 89 kg (5% - 7%) but on our first short trip last week I was only able to get up to just under 70kg. It was my first time towing and I did not feel secure with the drive - I think the van was pitching - tugging and pushing at the car. Is that a normal feeling or do I need to sort the nose weight out?
