Complete Buying Guide for Onboard RV Generators
Essential Factors We Consider
When evaluating onboard RV generators, we focus on several key factors: power output (measured in watts), fuel type and efficiency, noise levels, portability, runtime, safety features, and price. For RVs, you’ll need enough power to run essential appliances like refrigerators, lights, and air conditioners. Consider whether you need continuous power or just backup capability. Fuel type affects both cost and convenience—gasoline is widely available but pricier, propane burns cleaner and stores longer, while natural gas offers the most economical option if available.
Budget Planning
Onboard RV generators range from budget-friendly inverter models around $300 to heavy-duty dual-fuel units exceeding $1,500. Consider not just the generator cost but also accessories like transfer switches, power cords, and fuel containers. For occasional use, a mid-range inverter generator offers the best value. For frequent off-grid camping or full-time RV living, investing in a higher-capacity model with electric start may be worthwhile. Don’t forget to factor in fuel costs and storage requirements for your chosen fuel type.
Final Thoughts
Choosing the right onboard RV generator depends on your specific needs, budget, and camping style. Inverter generators offer quiet, clean power perfect for electronics and small appliances, while conventional generators provide more power for larger loads. Dual-fuel models add flexibility, and tri-fuel options offer even more versatility. Whatever you choose, proper installation, regular maintenance, and safe operation practices will ensure your generator serves you reliably for years of trouble-free adventures.
Frequently Asked Questions
Q: What size generator do I need for my RV?
A: The size of generator you need depends on your RV’s power requirements. Calculate the total wattage of all appliances you want to run simultaneously, plus 20-30% for startup surges. For small RVs with basic needs, a 2,000-3,000W inverter generator may suffice. Larger RVs with air conditioning, multiple appliances, and electric water heaters may require 5,000-8,000W or more.
Q: Can I install a generator inside my RV?
A: It’s not recommended to install generators inside RVs due to dangerous carbon monoxide buildup. Generators should always be placed outside, at least 20 feet away from living areas. If you must have an onboard generator, consider a properly installed external generator with a transfer switch and CO detector system.
Q: How often should I run my RV generator?
A: Regularly running your generator (at least once a month for 20-30 minutes) helps keep the engine lubricated and prevents fuel from degrading. This maintenance practice extends the generator’s life and ensures it’s ready when you need it most. Avoid letting the fuel sit for extended periods without use.
Q: What’s the difference between inverter and conventional generators?
A: Inverter generators produce cleaner, more stable power suitable for sensitive electronics, operate more quietly, and are generally more fuel-efficient. Conventional generators provide more power at a lower cost but are louder and produce power that may not be safe for all electronics. For RVs, inverter generators are often preferred for their quiet operation and clean power.
Q: How do I safely connect my generator to my RV?
A: Always use a manual or automatic transfer switch to connect your generator to your RV’s electrical system. Never backfeed your RV directly through the shore power inlet, as this is extremely dangerous and can damage equipment or cause injury. Follow all manufacturer instructions and local electrical codes when installing and operating your generator.
Choosing the right onboard RV generator transforms your camping experience from a worrying prospect to a confident adventure. Whether you need quiet power for electronics, reliable backup during storms, or extended off-grid capability, the generators on our list offer proven performance and value. Remember to match your power needs with your budget, consider fuel flexibility, and prioritize safety features.
