Help urgently needed please. We have a Carthago compact-line and I have destroyed the fridge vent cover on the roof by driving under a low bridge, so the ventilation unit is now exposed to the elements. Does anyone know whether we should cover it with plastic to keep the rain out (which means we then couldn’t use the fridge as it would be un-ventilated - not ideal while we are on hols in France) or whether rain wouldn’t worry it if it got in?
