caravan damp

We had our service done for the caravan this year and the front right hand side had some damp which they believed has been caused by water ingress through the window seals. So the caravan has been in and they said it had been caught just in time, I.E no structural damage and they’ve had it in...

Is there any specific caravan makes or models that are particularly bad when it comes to damp? If your caravan does have damp, will it dry out?
