How do you stop condensation in a hybrid trailer?

In this article, we will answer the following question: How do you stop condensation in a hybrid trailer? We will discuss the main causes of condensation in a hybrid trailer, and the best ways to beat it. 

​​How do you stop condensation in a hybrid trailer?

Stopping, or completely avoiding condensation in a hybrid trailer is unfortunately not possible because we have no influence on the weather conditions. There are different ways to reduce condensation, however:

  1. Ventilate. When buying a trailer, choose one with plenty of ventilation options. You can reduce condensation by using ventilation openings, for example by opening the ventilation windows or the door. Use multiple ventilation points, one is not enough. 
  1. A dehumidifier can also be the solution, it is a tank with granules that absorb moisture, condensation and unpleasant odours from the air. Check below our section on the best dehumidifier for a hybrid trailer.
  1. Hot climate? Keep the hybrid trailer closed during the day! Are you going to camp in a hot area of the country? Make sure to keep the trailer as closed as possible during the day and ventilate it at night when the outside temperature drops. At home, in hot weather, you also leave everything closed and ventilate only in the evening. “Evening air” contains much less moisture. 
  1. Keep wet things out of the trailer. Wet clothes or other wet items cause a lot of condensation. So leave them outside the trailer. Don’t you have the option? Pack wet items properly in a plastic bag so that air from wet items does not enter the hybrid trailer.
  1. Don’t cook in your trailer. At home, you always cook with the hood that sucks in the cooking vapours. When camping with a hybrid trailer, you obviously don’t have a hood. It is, therefore, preferable to cook outside. The hot air from the cooking rises and cannot come out because the polyester canvas does not breathe.
  1.  Avoid gas heating. As with cooking, a radiator also emits hot air, which increases the risk of condensation forming. So avoid heaters in your trailer.

How does condensation form inside a hybrid trailer?

Condensation can have at least five different causes:

  • Temperature differences. This usually happens during rain showers. During a rain shower the temperature outside has dropped rapidly and you yourself often stay in the trailer. The trailer canvas cools from the outside and the warm air from the inside condenses inside the canvas. Condensation can cover the entire surface of the roof and therefore cause a lot of water.
  • Exhalation/perspiration. At night you lose moisture while sleeping: on average 0.5 liters per person. If four of you sleep in a polyester trailer, for example, that means around 2 liters of water. This water will also condense against the outside.
  • Hot air. In the summer in many countries, the humidity of the air during the day is generally high. If warm air enters the trailer during the day, this air contains an extremely high amount of moisture and condenses as soon as it cools. When you cook in the trailer, you also get a lot of hot air in the trailer.
  • Wet or damp clothing. Were you outside during a rain shower and your clothes and shoes were soaked? Do not let them dry in your trailer, this will also cause condensation.
  • The land. The soil breathes too. If you place the trailer on a lawn, condensation/steam will also emerge from the grass. The taller the grass, the more condensation you get in your trailer.

How to remove condensation from a hybrid trailer?

Option 1: This is the most basic, use an absorbent cloth or cloth and remove condensation manually from bottom to top to prevent water from falling on the dashboard, furniture or floor, drain and repeat until the surface is complete.

Option 2: Especially for the driver’s window. Use the vehicle’s ventilation, start the engine and select the demisting on the ventilation controls (the symbol is a trapezoid that simulates the front window with arrows inside pointing upwards that symbolize the air) and select a warm or hot air temperature.

Option 3: Use a squeegee to drag the condensation onto an absorbent material.

Option 4: Ventilate the vehicle, if the outside temperature and environment are drier than inside, open the windows and/or doors and wait for the condensation to dry or evaporate.
