We have an Autotrail Scout and seem (the motorhome not us!) to be suffering from a leaky rear lounge sunroof. It's been fixed twice by a dealer last year by resealing but the problem appears to have returned. It only happens when we're driving as its dry as a bone when static even under the most extreme downpours. The water seems to be blowing underneath and dripping around the internal fittings. All appears okay up there when I check. Is this a common problem....has anyone else experienced this please?
