Buying Guide: Key Considerations For Dual Fuel RV Generators
- Power needs: Determine essential and optional loads (air conditioner, heating, fridge, outlets) and select a generator with adequate surge and running watts.
- Fuel availability and runtime: Propane is convenient for longer outings; gasoline provides higher power for peak loads. Consider fuel storage, availability at destinations, and expected runtime per tank.
- Portability and weight: For frequent mobility, prioritize lighter, compact models with durable handles; larger units may require a dedicated storage spot in the RV.
- Noise and comfort: Look for inverter generators with low decibel ratings and quiet technology, especially for campgrounds and nighttime use.
- Power quality: Inverter technology delivers clean sine waves suitable for sensitive electronics, reducing the risk of damage.
- Safety features: CO sensors/shutdown, low-oil alerts, automatic shutoffs, and remote or electric start add safety and convenience.
- RV compatibility: Ensure outlets include RV-specific 30A/TT-30R or 50A configurations and consider parallel capability if you anticipate needing extra power.
- Fuel system features: Look for fuel shutoff valves for safe storage and long-term maintenance, as well as easy-start systems and remote starts when available.
- Warranty and service: Favor brands with strong customer support and widely available parts or service networks.
- Budget vs. performance: Weigh the upfront cost against wattage, runtime, noise, and added safety features to pick the best value for your travel style.
