I'm considering getting a couple of those moisture trap things (plastic box with granules in the bottom to attract moisture in the air)for my caravan over the winter months while its not in use.

Anyone have any opinions on them?

I've read a couple of comments before, some good and some bad, just thought I would ask.

i have 3 of the unibond type that take a disc of calcium carbonate. the disc slowly disolves with the moisture in the air. the tank fills up with some pretty nasty liquid that is an irritant. if you spill it it never dries.

the verdict is open as to whether they actually keep the air or the rest of the caravan drier.

i also have an electric dehumidifier and this really does dry out damp but i keep my caravan in storage so cant run an electrical supply to it. but i have kept my caravan on my drive before for 2 weeks with the dehumidifier and a strategically placed fan heater running and dried out a damp patch (after i repaired the leaking seal).

one problem with the chemical dehumidifiers is that the collected water stores cold energy. the temperature drops at night then warms up in the day. the water condenses on the outside of the tank like it does on a cold pint glass. the water then runs off onto the surface its on so its wise to stand it on a tray or a sheet of kitchen paper.

IMHO they are a waste of time unless you block up all the vent holes in the caravan. but then yoiu need to remember to unblock them when you next use the caravan.
If you do not block up the vents, as the caravan air dries, it draws in more moist air from outside so you end up trying to dry the atmosphere.
Your choice.

In 44 years of owning caravans find a total waste of time. I put some in a few years ago and were bone dry at the end of winter.If they do collect any moisture I would think the caravan has a serious damp problem that needs repair.

Also been caravanning 30 years and never used these and my various vans in that time have not suffered. Complete waste of time and money

Ventilation is most important so you have a good flow through of air. All you are doing with a moisture trap is collecting water that would otherwise flow straight out of the caravan.

We keep our van in storage,any ideas of how I can keep good ventilation, or do I need to make regular visits and open as many windows for as long as possible

It has floor vents, that's enough.

The caravan should have ventilation grilles in the floor inside some of the cupboards. Ensure cupboards are open so vents are open to rest of caravan. Toilet will have permanent ventilation so leave toilet door open. Roof lights also have permanent ventilation around edges so all that is sufficient.

Leave cushions standing on edge to allow air to circulate under dinettes. All that is good enough I find. If you can open up windows & roof lights for a bit on a dry day so much the better.

I think we would all agree that they most certainly will not resolve problems with a caravan that is leaking.

I personally use them together with a cover (many different views on these as well)and only expect them to help reduce that musty smell that can build up.

My view is that they are cheap as chips and certainly do no harm.

It's your choice.

We keep our van at home, and like others ventilation is key, on a nice dry day I like to make a brew go sit in the van with the door open and some roof lights, and pretend I am away somewhere warm and sunny (whilst wrapped up lol)

Talking to someone that keeps their van in storage, and it closes in winter so they cannot access it from January until March, they told me they keep the windows on night lock to help ventilation.

I put some in ours . I also used to use dishes of salt .
Some years they are wet and some times they have been dry . I think it depends on whether it is a very wet winter with lots of rain or freezing cold and dry .
