I am towing a 19ft Retreat van and experiencing considerable sway, when something big (B-Doubles etc) pass me. I am running the tryes at 42PSI on the MUX and have a Hayman Reece leveller system fitted. I am also running the caravan tyres at 42PSI and the dual axel system is fitted with a Dexter Anti Sway Control. So I feel I am doing all the right things. Any ideas?
