How Do You Choose the Best Dual Fuel Generator for Your RV?
To choose the best dual fuel generator for your RV, consider factors such as power output, fuel efficiency, portability, noise level, and additional features.
Power output: Determine the total wattage your RV requires. Calculate the wattage of essential appliances like air conditioners, refrigerators, and lights. For example, an average RV air conditioner may need around 2,000 to 3,000 starting watts. A study published by Energy Star (2023) suggests planning for about 30% more capacity than your calculated needs to ensure optimal performance.
Fuel efficiency: Look for a generator that uses fuel wisely. Fuel consumption is typically measured in gallons per hour at a specific load. A dual fuel generator that can run on propane and gasoline can provide flexibility based on availability. According to a report by Generator Magazine (2022), propane is often more efficient than gasoline, leading to longer run times.
Portability: Assess the generator’s weight and size. If you plan to travel frequently, choose a compact model with wheels for easy transport. Many generators weigh between 50 to 100 pounds. A study by Portable Power Dynamics (2023) indicates that lighter models are often favored for RV use due to their easy handling.
Noise level: Generators produce varying noise levels measured in decibels (dB). Look for models designed to operate quietly, ideally under 60 dB. According to Quiet Power Research (2022), quieter generators can enhance the camping experience by reducing noise disturbances.
Additional features: Evaluate features that enhance convenience and safety. Options like electric start, automatic shut-off, and multiple outlet types increase usability. Some generators also come with inverter technology, which provides cleaner power for sensitive electronics. A survey by RV Tech Insights (2023) highlighted that users prefer models with built-in overload protection and fuel gauges for ease of monitoring.
What Key Features Should You Look for in Portable Dual Fuel Generators?
When looking for portable dual fuel generators, consider the following key features:
| Feature | Description |
|---|---|
| Fuel Flexibility | Ensure the generator can run on both gasoline and propane for versatility. |
| Power Output | Check the wattage ratings for both starting and running power to meet your needs. |
| Runtime | Look for a generator with a long runtime on both types of fuel. |
| Portability | Features like wheels and handles enhance mobility. |
| Noise Level | A quieter generator is preferable, especially for home use. |

Why Are Inverter Models Considered the Best for RV Use?
Inverter models are considered the best for RV use due to their ability to provide clean, stable power efficiently. They are particularly well-suited for sensitive electronics commonly found in recreational vehicles.
According to the U.S. Department of Energy, inverters convert direct current (DC) to alternating current (AC). This conversion allows RVs to power standard appliances and electronics while maintaining energy efficiency.
Inverter models excel because they produce a pure sine wave output. This output mimics the power supplied by utility companies, ensuring consistency and reliability for delicate devices like televisions and computers. Additionally, inverter generators tend to be quieter and more fuel-efficient than conventional generators, which makes them ideal for camping and outdoor activities.
Technical terms such as “sine wave” need clarification. A pure sine wave is the smooth, oscillating wave that represents the ideal electrical power form. It enables appliances to operate without risk of damage from power surges or fluctuations which can occur with less refined power sources.
The mechanism behind inverter operation involves two key processes: inversion and rectification. First, the inverter rectifies DC power from the vehicle’s battery into AC power. Then, it modulates this power into a sinusoidal wave. This ensures that the energy produced is suitable for all types of electronic devices.
Specific actions that enhance the effectiveness of inverter generators include regular maintenance and choosing the right-sized inverter based on electrical needs. For example, using a generator rated for at least 20% above the total wattage of the appliances ensures reliable performance. Scenarios, such as dry camping or using RV air conditioning units, further illustrate how inverters provide essential power stability without excessive noise or fuel consumption.
What Are the Top Recommended Dual Fuel Generators for RVs?
Here are some of the top recommended dual fuel generators for RVs:
| Generator Model | Peak Watts | Running Watts | Fuel Type | Weight (lbs) | Runtime (hours) |
