The best generator for a travel trailer depends entirely on your power needs, budget, and camping style. For most RVers, a quiet and efficient inverter generator in the 2,000-3,000 watt range offers the ideal balance of power, portability, and minimal noise disturbance.
Understanding Your Travel Trailer’s Power Requirements
Before diving into specific models, it’s crucial to assess your power demands. Ignoring this step can lead to frustration, wasted money, and potential equipment damage.
Calculating Your Wattage Needs
Start by listing all the appliances and devices you plan to use simultaneously. Common RV appliances include:
- Air Conditioner: Typically the highest wattage draw, ranging from 1,500 to 2,500 watts for startup and 500-1,000 watts for running.
- Microwave: Around 600-1,500 watts.
- Refrigerator: Varies greatly, but often around 150-200 watts running, with a higher startup surge.
- Television: 50-200 watts.
- Lights: LED lights consume very little power.
- Small Appliances (coffee maker, toaster): 600-1,200 watts each.
- Water Heater (electric): Can draw significant power, around 1,500 watts.
Add up the running wattage of all appliances you expect to use simultaneously. Then, identify the appliance with the highest startup wattage (usually the air conditioner) and add the difference between its startup and running wattage to the total. This gives you the peak wattage required. Choose a generator that can handle both your continuous and peak wattage demands. It’s always better to err on the side of caution and select a slightly larger generator than you think you need.
Types of Generators: Inverter vs. Conventional
-
Inverter Generators: These produce cleaner, more stable power suitable for sensitive electronics like laptops and smartphones. They are also significantly quieter and more fuel-efficient than conventional generators. Inverter generators are generally the preferred choice for travel trailers. They also often feature parallel capability, allowing you to link two units together to double the power output.
-
Conventional Generators: These are typically more affordable but produce less stable power and are significantly louder. They are often less fuel-efficient and heavier than inverter generators. While suitable for some applications, they are generally not recommended for travel trailers due to noise and potential damage to sensitive electronics.
Top Considerations When Choosing a Travel Trailer Generator
Several factors should influence your generator selection:
Wattage Capacity
We’ve already discussed calculating your wattage needs. Ensure the generator can handle both the running and starting wattage requirements of your appliances.
Noise Level
Noise is a critical factor, especially in campgrounds. Look for generators with a noise rating of 60 decibels or less. Inverter generators are typically much quieter than conventional generators. Consider the impact your generator’s noise will have on your neighbors.
Fuel Efficiency
Fuel efficiency impacts both your budget and the environment. Inverter generators often feature economy modes that automatically adjust engine speed based on the power demand, maximizing fuel efficiency.
Portability and Weight
Travel trailers have limited storage space. Choose a generator that is lightweight and compact for easy transport and storage.
Ease of Use
Consider features like electric start, remote start, and digital displays. Easy maintenance access is also important.
Price
Generators range in price from a few hundred to several thousand dollars. Balance your needs with your budget.
Safety Features
Look for generators with safety features like low-oil shutdown, overload protection, and spark arrestors.
Recommended Generator Models
While specific recommendations change frequently, here are general categories and considerations based on typical travel trailer needs:
-
Small Travel Trailers (minimal power needs): A 2,000-watt inverter generator is often sufficient. Look for models from brands like Honda, Yamaha, or Generac.
-
Mid-Sized Travel Trailers (with air conditioning): A 3,000-watt inverter generator is generally recommended. Consider models that offer parallel capability for future expansion.
-
Large Travel Trailers (multiple appliances): Two 2,000-watt inverter generators connected in parallel or a single 3,500-watt or larger generator might be necessary. Consider the weight and storage implications of larger units.
Always read reviews and compare specifications before making a purchase.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about choosing a generator for your travel trailer:
FAQ 1: Can I use a regular extension cord with my generator?
No. Use a heavy-duty extension cord designed for outdoor use and with the appropriate amperage rating. Using an undersized cord can cause voltage drop and damage your appliances or the generator.
FAQ 2: What is the best way to ground my generator?
Grounding is essential for safety. Connect the generator’s grounding terminal to a grounding rod driven into the earth. Follow the manufacturer’s instructions carefully.
FAQ 3: How often should I change the oil in my generator?
Follow the manufacturer’s recommended oil change schedule, typically every 50-100 hours of operation. Use the recommended oil type and viscosity.
FAQ 4: Can I run my generator inside my travel trailer?
Absolutely not! Generators produce carbon monoxide, a deadly, odorless gas. Always run your generator outdoors in a well-ventilated area, away from windows and doors. Install a carbon monoxide detector inside your travel trailer and test it regularly.
FAQ 5: How can I reduce generator noise?
Use a generator enclosure or sound dampening materials. Place the generator as far away from your campsite as possible (while still being safe and secure). Ensure the exhaust is directed away from your living area and your neighbors.
FAQ 6: What is parallel capability, and why is it useful?
Parallel capability allows you to connect two compatible generators together to double the power output. This is useful if you anticipate needing more power in the future or if you want to start with a smaller, more manageable generator and add a second one later.
FAQ 7: Can I connect my travel trailer directly to the generator?
Yes, use the correct amperage-rated RV power cord to connect to the generator’s outlet. Ensure the generator’s outlet matches your trailer’s connection type (typically 30 amp or 50 amp).
FAQ 8: What is the difference between surge wattage and running wattage?
Surge wattage is the maximum power the generator can provide for a short period (typically a few seconds) to start appliances like air conditioners. Running wattage is the continuous power the generator can provide.
FAQ 9: How do I store my generator when not in use?
Drain the fuel tank or use a fuel stabilizer to prevent fuel degradation. Store the generator in a dry, protected location. Follow the manufacturer’s instructions for long-term storage.
FAQ 10: What are the advantages of propane-powered generators?
Propane-powered generators typically run cleaner than gasoline-powered generators, produce fewer emissions, and require less maintenance. Propane also has a longer shelf life than gasoline. However, propane generators may be less fuel-efficient and require a propane tank.
FAQ 11: Are there any “eco-friendly” generator options?
While all combustion engines have environmental impacts, some generators are more efficient and produce fewer emissions than others. Look for generators with EPA and CARB certifications. Consider solar power as a supplementary or alternative energy source.
FAQ 12: What maintenance is required for a travel trailer generator?
Regular maintenance includes oil changes, air filter cleaning or replacement, spark plug inspection and replacement, fuel filter replacement, and general cleaning. Refer to the manufacturer’s manual for specific maintenance recommendations. Following the maintenance schedule will extend the life of your generator and ensure it operates efficiently.
