Buying Guide
- Fuel type and runtime: Gasoline units are common and light, but dual-fuel models extend options when propane is easier to source. Compare run times at half load to estimate daily needs on the road.
- Noise and weight: RV life benefits from quieter models and lighter units, especially for campgrounds with strict noise rules. Look for decibel ratings around 60-65 dBA or lower for comfortable operation at a campsite.
- RV readiness: Ensure the generator has a dedicated RV outlet (TT-30R or similar) and is capable of parallel operation if you anticipate needing extra power for multiple devices.
- Safety features: CO monoxide sensors, automatic shutoff, and proper outlet protection are important for enclosed spaces, especially inside RVs or yurts.
- Portability and ease of use: Look for wheels, folding handles, and straightforward recoil or electric start to simplify setup at campsites.
- Maintenance and support: Check warranty terms and availability of replacement parts. Parallel kits and accessory options should be sourced from the same brand when possible for compatibility.
- Power management: If you plan to run high-draw appliances or multiple devices, consider a model with higher peak and sustained outputs and a reliable voltage regulator to minimize surges.
