Condensation is a common issue faced by camper owners. It occurs when warm, moist air inside the camper comes into contact with the cold glass of the windows, leading to the formation of water droplets. This can cause several problems, including mould and mildew growth, corrosion, and reduced visibility. To prevent condensation, it is important to reduce indoor humidity levels and improve ventilation. This can be done by using dehumidifiers, opening windows, installing vents, and avoiding activities that increase moisture levels, such as cooking and showering indoors. Additionally, using window insulation film or thermal curtains can help reduce the temperature difference between the inside and outside of the camper, thereby reducing condensation.

What You'll Learn
Improve ventilation
One of the most important things you can do to prevent condensation in your camper is to improve ventilation. This will help to reduce the amount of moisture in the air and prevent it from building up and causing condensation on your windows.
Firstly, make sure you are using the vents in your camper effectively. If you have a vent fan above your stove, use it when cooking to remove steam from the air. Similarly, use the vent in your bathroom when taking a shower to reduce moisture levels. If your stock vent fan isn't working well, consider investing in a replacement RV vent fan that fits the standard 14″x14″ roof opening to help improve airflow.
Another way to improve ventilation is to open your windows. Leaving windows open during the day will allow dry outdoor air to enter your camper and moist indoor air to escape. Opening windows for at least 15 minutes after cooking or taking a shower can help prevent condensation. If you're camping in a cold location, you may want to avoid opening your windows, as this will let cold air in and could make your camper uncomfortably cold.
In addition to using vents and opening windows, you can also improve ventilation by using exhaust fans. Exhaust fans in bathrooms and kitchens can help to remove excess moisture from the air when showering or cooking. Make sure these fans vent to the outside, rather than into an attic or wall cavity. If your exhaust fans are too small, they may not be effective at removing moisture, so consider upgrading to more powerful fans.
Finally, consider installing a radon mitigation system, which can help to improve overall ventilation in your camper.

Use a dehumidifier
Dehumidifiers are an effective way to reduce moisture in the air and keep your camper windows from sweating. They are designed to "suck" the moisture out of the air and keep humidity levels low. This is especially useful if you are camping in an area with high humidity and lots of rain.
Dehumidifiers come in various sizes, from small portable ones to larger units designed for 1500 sq. ft. homes. Choose one that is appropriate for the size of your camper. Look for a dehumidifier with a built-in hygrometer to monitor humidity levels. Some advanced models automatically adjust their operation based on the detected humidity, ensuring optimal performance.
When selecting a dehumidifier, consider its power source. Some dehumidifiers run on 120-volt AC electricity, so they will work in your camper if you are connected to shore power or have a generator.
Make sure to empty the water collected by the dehumidifier regularly. Some dehumidifiers come with a tube that you can drain directly outside, while others have a bucket that needs to be emptied manually.
In addition to using a dehumidifier, you can also improve ventilation in your camper to reduce indoor humidity levels. Open windows, use vent fans, and avoid cooking or showering inside the camper to minimise moisture buildup.
By using a dehumidifier and improving ventilation, you can effectively reduce the amount of moisture in your camper and keep your windows from sweating.

Insulate windows
Insulating your windows is an easy DIY project that can help reduce window moisture and lower your energy bill with added energy efficiency.
Firstly, you can apply a window insulation film to the exterior of your windows. This plastic layer helps to reduce condensation by preventing cold air from reaching the glass and creating warm, moist air. It acts as a barrier, keeping the cold air out while allowing light in. It is also relatively inexpensive and easy to install.
Another option is to attach thermal curtains to the inside of your windows. These curtains are made of special materials that keep heat inside and block out the cold air from outside. They are a great way to keep warm air inside your camper and help to reduce condensation.
Additionally, you can improve the insulation of your windows by caulking or weather stripping them. This simple project can be done by purchasing caulk or weather stripping at your local hardware store and following the instructions for installation.
You can also create your own version of double-pane" windows by adding plastic window film to the inside of your windows. This sealed layer of air between the plastic film and the glass window makes an insulating "air blanket" and can prevent the warm inside air from contacting the cold window.
Finally, if you have double-paned windows and notice condensation between the panes, you likely have a seal leak. Contact a local window service professional to discuss repair options.

Wipe down windows
Wipe down the windows in your campervan regularly to prevent condensation from building up. Use a soft cloth or squeegee to wipe down the windows, and make sure you get into all the corners and crevices. This will help to remove any moisture that has built up and prevent it from worsening.
It is also important to dry the towel outside after wiping down the windows, as this will help to reduce the amount of moisture inside your campervan.
In addition to wiping down the windows, you can also try using window insulation film or attaching thermal curtains to the inside of the windows. These curtains are made of special materials that keep heat inside and block out the cold air temperature from outside, reducing condensation.
Another way to reduce condensation is to improve ventilation in your campervan. Open windows during the day to allow dry outdoor air to circulate inside, and use vent fans to draw moisture out.
Finally, you can try to reduce indoor humidity levels by using a dehumidifier. Dehumidifiers are designed to remove excess moisture from the air and keep humidity levels low, preventing condensation from forming.

Avoid camping in winter
Condensation is a common issue in campers and RVs, and it is often made worse by cold weather. Therefore, one of the best ways to prevent condensation on your camper windows is to avoid camping in the winter months.
Winter weather is typically colder and wetter, providing the perfect conditions for condensation to form. When the warm, moist air inside your camper comes into contact with the cold windows, condensation occurs. This can happen more frequently in winter, as you are less likely to open windows for ventilation or spend time outdoors due to the cold temperatures.
Camping in the winter also increases the risk of frozen pipes, and condensation can lead to more serious issues such as mould and mildew growth, window damage, reduced visibility, and a less comfortable indoor environment.
If you do choose to camp in the winter, ensure you have a well-insulated camper or RV designed for cold weather conditions. Taking steps to reduce indoor humidity levels, such as using a dehumidifier or improving ventilation, can also help prevent condensation.
In addition to avoiding winter camping, you can try other methods to keep your camper windows from sweating. Here are some additional tips to prevent condensation:
- Use window insulation film or attach thermal curtains to the inside of your windows.
- Improve ventilation by opening windows, using vent fans, and keeping cabinet and closet doors open.
- Wipe down windows regularly to remove any moisture buildup.
- Hang wet items outside to dry instead of inside the camper.
- Avoid cooking and showering inside the camper, as these activities release moisture into the air.
- Use an electric space heater to keep the air inside warm and reduce condensation.
