Tips for How To Keep Your Motorhome Cool in Summer

If you want to keep your motorhome cool in the summer, there are a few things you can do. Here are some tips for keeping your motorhome cool in the summer:

  1. Park in the shade: Parking your motorhome in a shaded area can significantly reduce the amount of heat that enters your motorhome. Look for shady spots in campgrounds or use a portable shade canopy to create your own shade.
  2. Use Reflective materials: Reflective materials, such as window coverings, can help block the sun’s rays and prevent heat from entering your motorhome. Consider using reflective shades or curtains for your windows and windshield.
  3. Install Insulation: Insulating your motorhome can help keep the interior cool by reducing heat transfer. There are several types of insulation available for motorhomes, such as fiberglass, foam, and reflective insulation. Consult with a professional to determine the best insulation for your motorhome.
  4. Upgrade Air conditioning: If your motorhome’s air conditioning unit is not providing adequate cooling, consider upgrading to a more efficient unit. Look for an AC unit with a high SEER rating (Seasonal Energy Efficiency Ratio) for maximum cooling efficiency.
  5. Keep Windows and Doors Closed: Keep your windows and doors closed during the hottest parts of the day to prevent hot air from entering your motorhome. Open them during the cooler parts of the day or at night to allow for natural ventilation.
  6. Use Fans and Ventilation Systems: Fans and ventilation systems can help circulate cool air and remove hot air from your motorhome. Consider installing ceiling fans or portable fans, and make sure your motorhome’s ventilation system is functioning properly.


Proper ventilation is key to keeping your motorhome cool in the summer. Make sure to open the windows and vents when you’re parked in a shady spot, and keep them closed when you’re in the sun. This will help to circulate the air and keep the temperature inside your motorhome from getting too hot.

Adequate Insulation

Making sure your motorhome is properly insulated is also important for keeping it cool in the summer. Make sure you check for any gaps in the insulation and fill them in with foam or other materials. This will help keep the heat out and keep your motorhome cool.

Motorhome Fans

A great way to keep your motorhome cool is to install motorhome fans. These fans will help circulate the air and cool down the temperature inside your motorhome. You can find motorhome fans in a variety of sizes and styles, so you’re sure to find one that fits your needs.

Air Conditioning

If you’re looking for a more efficient way to keep your motorhome cool in the summer, you may want to consider installing an air conditioner. Air conditioners are designed to keep the temperature inside your motorhome cool, so you can stay comfortable even in the hottest months.

We have the Totalcool 3000 Portable Cooling System, which is tri voltage 12v, 24v & AC mains power, making it great for motorhomes, and is also lightweight and compact so it doesn’t take up too much space.
