Dehumidifiers

Nor us, sometimes there is some condensation which is why we keep the van well aired.

We've never used dehumidifiers in the caravan either.  To try and take moisture out of the air seems a bit like an impossible task, to be honest.  I don't see that it does much good. 

If you are worried about damp, I think it would be fair to say that most 'destructive damp' is caused by water ingress.

If the air coming into the van, and it will, has a high moisture content than that in the van then those dehumidifying things are a total waste of money and time! And to be honest, that's most of the time! Like pushing pound notes down the drain!

We have campervan on driveway.Access to 13 amp hook up.Use van all year.However we have an electric dehumidifier and will use it now and again in winter plus a blow heater, We dont remove any bedding etc.and never had  any problem with damp/condensation or mould. Likewise on good dry days will open all the doors to give a good airing.

if you can hermetically seal your van than that may work, if not Canute may be worth callng for! The air moisture content entering and leaving will always balance out!

But evey little bit may just reduce the absorbtion of moisture by those materials which will retain it! Removing them may be a better option and definitely a cheaper one!.

Is it a bit like having a heater in an awning?

We've never had a damp problem and never use gel sachets or humidifiers. I have occasionally put on a heater for an hour or so when the van has been sat for a week or two in very cold weather. Otherwise we use the van throughout the year. As others have said, it needs to be active. I do leave off the handbrake and use chocks on the drive.

Design of your motorhome will have a big part to play in what you should do. If cushions are against the wall and not against a board that provides an air gap, then I would consider removing the cushions or at least keeping them away from the wall. Removing food to discourage mice is another must do. If you check the van at least weekly, you'll soon see the early signs of internal condensation. That's when you deal with it.

Humidifiers -- A complete waste of time. Open the windows. door and the roof vents every few days to let the van be filled by fresh air ..

The only dampness you have  to worry about is if your van has a water leak ( Common to certain models from all British manufacturers) then you have to have the dealer put it right ASAP.

use cat litter

I wouldn't worry. We leave our MH 2-3 weeks between trips, don't do anything to it other than drain down in case of frost, make sure nothing damp is left inside, give it a good clean, then periodically go in once or twice a week to let some air in, check things over, sit and have a cup of tea, get it ready for next trip! Using a MH regularly seems to be the key to keeping things working fine. We are lucky to be able to keep MH at home, and to be able to use it frequently. Ours is having its MOT tomorrow, fingers crossed!
