How to Keep a Travel Trailer Cooler

How to Keep a Travel Trailer Cooler
The temperature inside a travel trailer is directly related to the outdoor temperature. When you add heat from appliances and the engine, passengers can really start to feel overheated and in need of a cooling system. Depending on your needs, there are a few options you can take to cool your travel trailer when temperatures start to rise.


Difficulty: Moderate

Things You’ll Need:
  • Generator
  • Air conditioner
  • Cooling fans
Step 1
Mount a platform to the rear of the travel trailer and install a portable generator if one is not already installed. Choose a 4 kw generator, which is equal to 4,000 watts or 33.3 amps, so you have sufficient power to operate several appliances at the same time. If you install a portable generator, use an adapter to connect the trailer plug to the generator receptacle.
Step 2
Install a 120 v roof air conditioner, which can use up to 13.5 amps of power. You can plug the air conditioner into a campground electrical post or use a generator while traveling on the road. Check the data plate on the air conditioner for the exact amount of amperage required to operate the air conditioner.
Step 3
Run individual cooling fans if additional cooling is needed or you wish to reduce the amount of power you are using. Position the fans in different directions so you can rotate cool air throughout the travel trailer.

Tips & Warnings

Keep all windows closed when an air conditioner is in use.
Re-seal cracks and spaces between the travel trailer roof and the air conditioner using caulk to improve the efficiency of the air conditioning system.
Park your travel trailer in a shaded area to keep it cool when it is not in use.
Never plug an air conditioner into an extension cord. Doing so could affect the amount of voltage that is used.
