I purchased a Kampa rally ace 400 last March and noticed after a few days of using it that the interior roof lining appeared to have mould appearing which gradually became worse during the 2014 season, I have contacted the supplier with photos who in turn contacted Kampa direct but they were not interested just said it was due to condensation, although the exterior roof is fine no problems at all. Having had a Kampa pro 390 previously for approximately 3 years with no probelms at all I am very disappointed with the response from Kampa. As this particular awning was new to the market I believe a different material has been used for the interior of this model. I would like to know if anyone else has had a similar problem to mine.
