My syndicate are pondering an electrical hookup and dehumidifier for our trailer that's kept over winter at a site that's humid and cold (it's probably in cloud for 50% of the winter).

The trailer is an older metal trailer with unsealed doors and a rotating air vent.

I'm wondering how effective a dehumidifier can be in these conditions? It is possible to reduce the humidity in a non-sealed trailer or do you end up trying to dehumidify the world's atmosphere what with relative humidity and equilibrium as it is?

Go to West Marine website and see dehumidifier offerings. We have had good results with Damp Rids used with a low wattage heater such as Goldenrod. West Marine also has low wattage heaters with fans. Mildew inside boats is as big a problem as keeping glider trailers dry in humid climates. Yes, seal up the trailer.
