We have an Autotrail Tracker EKS. We park on level ground but find on driving off a deluge of water cascades off the roof at the front when starting off. It collects in front of the roof light and the higher moulding on the front. Is this normal? I think the problem can be alleviated by reversing onto our chocks. Anyone have a similar problem? I don't like the idea of a pool of water sitting there especially in winter, or am I being fussy?
