Buying Guide: Built In RV Generator Considerations
- Power needs: List essential devices and estimate total running watts. Choose a model with a comfortable margin above peak needs.
- Fuel flexibility: Dual-fuel options offer more reliability, but add weight and cost. Gas with ECO mode is common for RV use.
- Noise level: Aim for units in the quiet range for campground compatibility, especially for overnight use.
- Portability vs. capacity: Heavier units deliver more power; lighter options are easier to move around a small RV space.
- RV compatibility: Look for dedicated RV outlets (120V/30A or 50A) and proper safety certifications.
- Runtime: Larger fuel tanks extend run time, reducing refueling during trips. Consider whether you value longer operation or more compact design.
- Safety features: CO shutoff sensors and automatic shutoffs protect occupants. Consider models with low-oil and overload protection.
- Maintenance: Simpler engines can be easier to service on the road. Check warranty terms and local service availability.
