Even as a relative newcomer to caravanning, do I need a system to stop snaking? I ask after having had a bad experience last year when my van jack knifed on a motorway and needed extensive repair. When the van was off the road I saw a demo of ATC and decided to buy altho I now learn I need the system developed by BPW to suit my chassis. Problem is that since my stabiliser was changed from an Alko to Winterhoff during the repair the van has been as solid as a rock. Am I going to get anything more than peace of mind for £400 plus?
