I have owned My 2003 Abbey Archway Royale 550 for 2 1/2 years now and have just noticed the external roof seems to be floating and become detached from whatever it should be fixed to. It doesn't leak and there is no damp. When I bought the caravan from a local dealer it was in the showroom all nice and shiny and they valeted it before I took it home. Is 2 1/2 years a reasonable time for this type of room problem to occur or have they deliberately kept it quiet as they would have seen it when valeting.
