I have a lunar delta 1996 ish only been caravaning 3 years, and just had a recient srvice, inforomed by company that the van has damp readings of between 15 to 30 % highest mostly in the roof area. there are no visable damp signs at all. would the recent snow ice contribute to this ? would leaving a heater on with ventilation help reduce it ? or should I just crack on and forget about it ? ( due to the age and the cost of possible repaires, ) any opinions welcome,
Phill
