Summer adventures are all about freedom and open roads — but the Australian sun can turn your RV into a sweltering sauna fast. Keeping your RV cool isn’t just about comfort; it’s also about protecting your appliances, electronics, and interior finishes from heat damage.
Whether you’re camping off-grid or travelling the coast, these 10 expert RV cooling tips will help you beat the heat, conserve energy, and enjoy your trip in comfort.
1. Park Smart and Seek Out Shade
Your parking spot can make or break your cooling efforts.
-
Look for natural shade — trees, hills, or tall buildings that block direct sunlight.
-
Orient your RV wisely — face windows away from the sun to reduce radiant heat.
-
Use tools like WikiCamps or CamperMate to find shaded campgrounds.
If shade isn’t available, use an awning or shade screen like the Aussie Traveller Awning Collection. A shaded RV can stay up to 10°C cooler.
2. Block Sunlight with Reflective Window Covers
Windows are major heat sources. Installing reflective covers and thermal blinds keeps the sun’s rays out and the cool air in.
-
Try the VOOS Thermal Screen with Suction Caps Aluminized 3 Pcs for maximum reflection.
-
Pair it with Milenco’s Universal Internal Thermal Blind (MIL2110) for superior insulation.
-
Use blackout curtains to block UV rays and protect your interior.
This simple upgrade can lower your cabin temperature by several degrees.
3. Improve Ventilation for Better Airflow
Air circulation is essential to maintaining a comfortable RV temperature.
-
Keep roof vents open with covers to allow hot air to escape.
-
Cross-ventilate by opening windows on opposite sides of your vehicle.
-
Use a 12V fan like the Sirocco II Fan 12V / 24V to circulate air efficiently.
Good ventilation helps control humidity, reduces condensation, and makes every breeze count.
4. Upgrade to LED Lighting
Incandescent lights generate unnecessary heat. Replacing them with LED bulbs keeps your RV cooler and saves power.
LEDs use less energy, last longer, and give off minimal heat — perfect for off-grid travellers relying on batteries or solar.
5. Cook Outdoors to Reduce Indoor Heat
Cooking inside your RV can raise the temperature by several degrees. Instead, take your meals outdoors.
-
Use a portable BBQ or camp stove to prepare your food.
-
Store drinks and perishables in the myCOOLMAN 48 Can Zipperless™ Cooler 30L.
-
Try no-cook recipes on hot days to minimize indoor heat.
Outdoor cooking keeps your RV’s interior comfortable and enhances the camping experience.
6. Insulate Your RV for Maximum Cooling
Insulation works both ways — it keeps your RV warm in winter and cool in summer.
-
Install foam board or reflective insulation in doors and storage areas.
-
Seal gaps with weatherstripping or rubber seals.
-
Add thermal blinds like Milenco’s Thermal Blind MIL2110.
-
Use rugs or mats on the floor to reduce heat transfer.
Proper insulation helps your air conditioner work efficiently and saves energy in the long run.
7. Use Portable or Roof-Mounted Fans
Fans are essential for improving airflow and reducing heat buildup.
-
Roof-mounted fans pull hot air up and out.
-
Oscillating fans move air around efficiently.
-
Consider the Aussie Traveller Interior Fan 12V / 24V for powerful, energy-efficient cooling.
Combine fans with open vents for a steady, refreshing breeze.
8. Maintain Your Air Conditioner Regularly
A well-maintained air conditioner performs better and uses less power.
-
Clean or replace air filters every few weeks in summer.
-
Inspect ducts and vents for leaks or dust buildup.
-
Use a soft start device to ease power demands when using solar or generators.
-
Keep coils and exterior units clean to avoid overheating.
Routine maintenance keeps your RV cool and prevents costly repairs.
9. Check Seals Around Windows and Doors
Cool air escapes quickly through worn seals. Regular inspection prevents heat from creeping in.
-
Replace old weatherstripping or use foam tape to reinforce weak areas.
-
Add draft stoppers for sliding doors.
-
Seal window gaps for better insulation and efficiency.
This easy DIY fix can drastically improve your RV’s temperature control.
10. Plan Travel During Cooler Hours
When you travel matters. Driving during the hottest hours increases cabin heat and fuel strain.
-
Travel early morning or late afternoon to avoid peak sun exposure.
-
Avoid being on the road from 12 PM to 3 PM whenever possible.
-
Set up camp early so you can enjoy the shade and cooler air.
Smart travel timing helps reduce wear on your RV and keeps your journey enjoyable.
Bonus Tip: Add an Awning for Instant Shade
Awnings not only enhance outdoor comfort — they also reduce interior heat.
-
Install an extendable awning like the Aussie Traveller Awning Collection.
-
Add side panels or mesh shade cloths for extra UV protection.
This addition can reduce surface heat by up to 10°C and make your RV feel instantly cooler.
Stay Cool and Travel Smart
Keeping your RV cool in summer is easier than you think. With the right mix of shade, insulation, ventilation, and maintenance, you can travel comfortably while conserving energy.
From reflective window covers to portable fans and coolers, small adjustments make a big difference in comfort and efficiency.
