We have just purchased the Bailey 5 series - Provence and for the first time are considering buying a caravan cover. It appears that there are numerous covers on the market, Protec, Purple Line etc, to name but two. If anyone has had experience -good or bad of the new style breathable covers - fitting, any dmage to windows etc - it would be very much appreciated if you could share your experience with us given that they are not a cheap item and we would also not want to damage the caravan either. Sincere thanks in anticipation - Pete
