If it's anything like here in Aberdeen it's been exceptionally mild today (11 deg) after a night of frost so condensation is certainly possible but unlikely connected to dehumidifier.
I would wipe it dry and maybe treat with mould inhibitor but keep an eye on things. It has been a very wet and damp winter and caravans may well suffer. A good airing with door and all windows open on a day when the sun is out and a breeze is blowing will help a lot.
Its the good old scotish weather at work,nothing to worry about though,i did have less of it this year by leaving the blinds and curtains open so that, what sun we got would come through the windows and heat the inside up.

it is hard to believe that so much moisture is created in an empty caravan.
The moist air circulates naturally in & out of the caravan through the ventilation, I'm struggling to see the point of collecting some of that moisture & storing it inside the caravan.
Tentz, you and I have covered this old chestnut plenty of times.
There's no need for moisture traps, dehumidifiers etc at all. There is a means of ventilation designed into the van (rooflights, vents etc) which provide adequate venting of the van providing these vents aren't blocked. A bit of an airing periodically doesn't hurt, but isn't essential.
Like Tentz, I'm puzzled why anyone would want to actually trap moisture inside their van ...

As well is two words!
How does a sage know everything about everything? or does he? or does he just think he does?
Remember, if you buy something you bought it, not brought it.
isn't it better in a bowl than on the walls,furniture and bedding.
damp on bedding etc would create smells and mould.
The water in the bowl comes from the air passing over the salt & being absorbed by it. What difference does that make to the air passing over the walls, furniture & bedding? I think you are confusing a bowl of salt with an electric dehumidifier.
There are a lot of opinions on this issue. I am certainly no expert and have used crystals in the past. I have also used nothing some years and I also use an electric dehumidifier occasionally.
I keep my caravan in the back garden so I can check frequently and open up on fine days. I don't like the idea of containers of extracted water sitting in caravans for long periods but people will try anything if they have a bad experience of mould which can look dreadful and be costly to repair or affect value.
I believe the weather is a bigger factor and in wet winters with large fluctuations in temps, condensation / mildew is worse.
Caravan covers? Again conflicting opinions. Ventilation? Plenty is good except when away on a cold windy night when it is cursed.
I wish there was a definitive answer or published controlled tests.
As you can see for yourself the dehumidifiers have drawn moisture from the air stored it as water and this has then
vaporised and risen to the inner roof and condenced.
if you dont have a damp problem then there is no need to use a dehumidifier.
Dehumidifiers will draw moisture from the air for as long as there is water on the planet
1. Salt traps. A salt trap will also have the effect of creating salt-laden air. We all know how corrosion damages metalwork, especially aluminium, so you are probably doing more harm than good.
2. Mr Grumpy's condensation problem is probably caused by the dehumidifier itself. Condensation forms when warm air meets a cold surface. The caravan is well insulated, with a steady airflow through it all the time. How come then the caravan is warmer inside? Most probably because all dehumidifiers produce heat. Mr Grumpy, again would be better to do nothing, and save a shed load of electricity too.
our caravan has been in storage/unoccupied since november.
we know the best cure for a condensation problem is heating and ventilation. but we need to be in the caravan to impliment these.
we also know where the moisture comes from.
we've lifted the cushions and bed base so there are no blocked airways.
surely the moisture is better in a tub than on our caravan fabrics.
No, the best cure for condensation is not heating an empty caravan, it is likely to cause it. I'm not sure why you think the water that collects in your bowls of salt would otherwise collect in your fabric, there is not enough moisture in the air to make the fabric wet but obviously salt absorbs moisture over a period of time, giving you bowls of saline solution that you really don't want inside the caravan.
yep, +2, on what tentz sez, the more moisture you extract inside the van, the more will be replaced by drawing it in from the outside, via the air vents.
the only way this would work is to completely seal the van, which you would agree is almost impossible
