Maintaining a comfortable temperature inside your travel trailer while driving is crucial for an enjoyable journey, preventing discomfort and potential damage to your belongings. The key lies in a multifaceted approach combining strategic preparation, effective ventilation, and maximizing the efficiency of your cooling systems, while understanding the limitations of each method.
Understanding the Challenge: Heat Gain in a Moving Travel Trailer
Driving with your travel trailer introduces a complex heat equation. Sunlight beating down on the roof and sides, radiant heat from the engine and road, and the lack of natural shade all contribute to significant heat gain. Compounding the issue, the trailer’s insulation may not be sufficient to withstand prolonged exposure to intense heat. Furthermore, constantly opening and closing the door adds to the influx of hot air. Addressing this challenge requires a proactive strategy, starting even before you hit the road.
Pre-Trip Preparation: Setting the Stage for a Cooler Ride
Before you even turn the ignition, there are crucial steps you can take to minimize heat buildup during your drive.
Parking Strategically
When possible, park your travel trailer in shaded areas or facing away from direct sunlight for extended periods. Even a brief period of shade can significantly reduce the initial heat load. If shade isn’t available, consider using reflective covers on your windows and roof to deflect sunlight.
Pre-Cooling Your Trailer
If you have access to electricity the day before your trip, turn on your air conditioner and pre-cool the trailer to a comfortable temperature. This gives the interior a head start in fighting off the heat when you’re on the road. Alternatively, if the outside temperature is lower than inside, utilize fans to exchange inside and outside air.
Packing Strategically
Avoid packing heat-sensitive items like electronics, medications, and certain foods in your travel trailer if possible. If you must transport them, consider using a portable cooler or storing them in the air-conditioned cab of your tow vehicle. Dark-colored items will absorb more heat, so opting for lighter shades can help.
Maximizing Ventilation While Driving
Effective ventilation plays a vital role in dissipating heat and improving air circulation within your travel trailer.
Utilizing Roof Vents
Open your roof vents while driving to create airflow and help exhaust hot air. Consider installing vent covers that allow you to keep the vents open even during rain. This is particularly effective in moving air and reducing humidity, contributing to a cooler overall experience.
Opening Windows Strategically
Open windows on opposite sides of the trailer to create a cross-breeze. Be mindful of wind direction and speed, as opening windows on the wrong side can force hot air in. Consider using window screens to keep insects out while maximizing airflow.
Fan Power: Interior Circulation
Employing strategically placed fans helps circulate air and improve the cooling effect. Consider battery-operated fans or fans powered by your trailer’s 12V system. Position fans to move air across the floor and towards the roof vents, facilitating heat removal.
Optimizing Your Air Conditioning System
While running your air conditioner while driving is tempting, it requires careful consideration and planning.
Generator Requirements
To run your air conditioner while driving, you’ll need a generator powerful enough to handle the load. Ensure your generator is properly sized and maintained to avoid damage to your air conditioner or electrical system. Consider the noise factor of your generator, especially if traveling in areas with noise restrictions.
Battery Bank and Inverter
Alternatively, you could use a large battery bank and a powerful inverter to run your air conditioner for a limited time. This option is more environmentally friendly but requires a significant investment and careful monitoring of battery levels.
Understanding Limitations
Be aware that running your air conditioner while driving will significantly reduce your gas mileage. Weigh the benefits of a cooler trailer against the increased fuel costs.
FAQs: Addressing Common Concerns
Here are answers to frequently asked questions about keeping your travel trailer cool while driving:
FAQ 1: Is it safe to run my propane refrigerator while driving?
Yes, it is generally safe to run your propane refrigerator while driving, but it’s crucial to check your refrigerator’s manual and local regulations. Some jurisdictions prohibit operating propane appliances while in transit. Ensure your propane tanks are securely mounted and properly ventilated. Always turn off the propane supply when refueling.
FAQ 2: Will reflective window covers really make a difference?
Absolutely! Reflective window covers act like a shield, reflecting a significant portion of the sun’s rays and preventing them from entering the trailer. This can substantially reduce the internal temperature, especially during peak sunlight hours. They’re an inexpensive and effective solution.
FAQ 3: What size generator do I need to run my RV air conditioner?
The size of the generator depends on the BTU rating of your air conditioner. Typically, you’ll need a generator that can provide at least 3000 watts of continuous power, but it’s always best to consult your air conditioner’s manual for the specific requirements. Remember to account for the surge wattage needed when the air conditioner initially starts.
FAQ 4: How can I improve the insulation in my travel trailer?
Improving insulation can significantly reduce heat gain. Consider adding insulation to your walls, roof, and floor if possible. Sealing any cracks or gaps around windows and doors with weather stripping can also help prevent hot air from entering.
FAQ 5: Are there portable air conditioners designed for travel trailers?
Yes, there are portable air conditioners designed for RV use. These units are typically smaller and less powerful than roof-mounted air conditioners but can be a good option for smaller trailers or supplemental cooling. Ensure the portable air conditioner has a proper exhaust vent to remove hot air from the trailer.
FAQ 6: How effective are RV awnings in keeping the trailer cool?
RV awnings provide shade over the side of your trailer, preventing direct sunlight from hitting the walls and windows. This can significantly reduce heat gain, especially on the sunny side of the trailer. They are a simple and effective way to create a cooler environment.
FAQ 7: Can I use a swamp cooler (evaporative cooler) in my travel trailer?
Swamp coolers can be effective in dry climates, but they are less effective in humid conditions. They work by evaporating water, which cools the air. However, they can also increase humidity levels inside the trailer, which may not be desirable in already humid environments.
FAQ 8: What is the best way to cool down my trailer at night without air conditioning?
Utilize natural ventilation by opening windows and roof vents. Use fans to circulate air. Park in shaded areas if possible. Consider using a portable swamp cooler if you’re in a dry climate. Sleeping on breathable sheets and wearing lightweight clothing can also help.
FAQ 9: Will driving faster make my trailer cooler?
Driving faster will not significantly cool your trailer. While increased airflow through open vents might have a slight effect, the increased engine heat and wind resistance will likely negate any benefits. Focus on other cooling strategies.
