Buying Guide: How to Choose the Right RV Generator
- Power needs: Calculate your essential loads (refrigerator, lights, CPAP, microwave, water heater) and match them to running watts. For RVs, aim for at least 3000–4000 running watts for common setups, with 4500–5000 peak watts for comfort.
- Fuel type and availability: Gasoline is common, propane offers longer shelf life, and dual-fuel models provide flexibility in variable fuel markets.
- Run time: Look for larger fuel tanks or efficient inverters to maximize hours between refuels, especially for boondocking.
- Portability: Consider weight, size, and built-in wheels or handles for easy transport to your RV site.
- RV readiness: Ensure you have a TT-30R 30A receptacle and appropriate outlets to power RV systems safely.
- Safety features: CO sensors, low-oil shutdown, and proper outlet covers reduce risk during operation.
- Sound level: Inverter generators are typically quieter; if you camp near other RVs, prioritize compact, low-decibel units.
Frequently Asked Questions
- What running watts do I need for typical RV living? Most RVs require 3000–4000 running watts to power essentials like fridge, lights, and a few appliances.
- Are dual-fuel generators worth it for RVs? Dual-fuel options provide flexibility when gas stations are scarce or propane is more available.
- Is CO monitoring important for RV generators? Yes. A CO sensor adds a safety layer when running a generator in enclosed spaces or near living areas.
- Should I choose an inverter or conventional generator? Inverters are generally quieter and better for sensitive electronics; conventional units often offer higher surge power but louder operation.
- How do I determine the right outlet types for my RV? Ensure the generator provides TT-30R 30A RV outlets and standard 120V outlets to cover essential devices.
- What maintenance is typical for RV generators? Keep oil levels, air filters, and spark plugs in check, and follow the manufacturer’s servicing intervals.
