member daveat28, Caravanner two green stars [Online] Posted 12 February 2013 by daveat28 Quote | Report We have a one year old Swift Challenger Sport and it has just come back from its first service. Unfortunately they have found 30% damp by the sky light and 30-100% damp in the corner above the fixed bed. Our dealers say it is the worst damp they have ever seen in a one year old van. The caravan is obviously going back to Swift! I'm just after some advice of what to expect while we go through this process with Swift. Many thanks. Post liked!
