Buying Guide
What should you consider when choosing an onboard RV generator?
- Power needs: Match running watts to your RV’s appliances, heating, and essentials. If you have air conditioning or a heater, calculate peak loads before selecting.
- Fuel type and efficiency: Gasoline units are common; dual-fuel options add versatility. Look for ECO or quiet modes to maximize run time.
- RV readiness: Ensure outlets include RV-ready ports (30A or 50A) and proper safety features like CO detectors and automatic shutdowns.
- Portability vs. footprint: Larger units deliver more power, but weigh more and may require a tow or stable setup. Consider noise level for campground etiquette.
- Safety features: CO shutoff, low-oil shutoff, and automatic restart or remote start options add reliability in remote locations.
- Maintenance and support: Availability of accessories, spare parts, and service centers influences long-term value.
Practical buying questions
- Do I need a dedicated RV-ready output (30A/50A) or are standard household outlets sufficient for my setup?
