I’ve been kicking around the idea of getting a dehumidifier for the cold damp west coast trips
One of the keys for winter RVing is dealing with humidity and condensation. When it was 5F at Trinidad Lake State Park, we woke up with condensation frozen in a sheet across the big windows over the dinette and sofa. So…we bought an electric dehumidifier.We chose the Eva-Dry Edv-2200 Mid-Size Dehumidifier from Amazon with a capacity larger than needed for the area because it needs to dehumidify quickly during the night. We also insulated the windows as you’ll see below.
Don’t forget how much moisture cooking releases into the air! If your range vent vents to the outside, it’ll help manage humidity and condensation inside…but then you lose some heat, and the flap outside can make some noise when it’s windy. Water vapor is actually a byproduct of burning propane, so using the range or oven produces humidity, as do propane heating appliances that aren’t vented outside. It may be good to put the dehumidifier near the stove if you have room.
