Customer Reviews
Customer Review: “Strong storm cell came through our area; high winds and driving rain. Moved in and out quickly so everything seemed normal. A few hours later, power went out. Power was out 9 hours. The 1300EH fired right up and ran 8 hours on a full tank of fuel (gas). That seems to be the average time I get on a tank of gas.”
Customer Review: “I only write reviews when I really like something or really hate it. I really like this generator, the DuroMax 12kW. I considered buying a permanent standby generator but I couldn’t justify the $20,000 expense (that’s what I was quoted by several suppliers here in Naples FL). That said, the Florida power grid is very unreliable and this generator gives me peace of mind.”

Complete Buying Guide for Built-In RV Generators
Essential Factors We Consider
When evaluating built-in RV generators, we look at several critical factors that determine real-world performance and usability. Power output (measured in watts) is the most important consideration – you need enough capacity to run your essential appliances simultaneously. We also evaluate fuel efficiency, runtime on a single tank, noise levels (especially important for campsite use), portability, and safety features like automatic shutoff systems.
Budget Planning
Built-in RV generators range from budget-friendly inverter models under $500 to high-capacity dual fuel units over $2,000. Entry-level models ($300-800) work well for basic needs and small RVs, while mid-range units ($800-1,500) offer better features and power. Premium models ($1,500+) provide massive output and durability for large RVs and serious backup needs. Remember to factor in fuel costs, maintenance, and potential installation expenses when budgeting.
Final Thoughts
Choosing the right built-in RV generator comes down to matching your power needs with your lifestyle. Smaller RVs can get by with inverter generators under 3000 watts, while larger units need 5000+ watts for comfortable operation. Dual fuel capability adds flexibility but increases cost. Always prioritize safety features and clean power output for your electronics. The best generator for you depends on your RV size, power requirements, budget, and how often you’ll use it.
Frequently Asked Questions
Q: How much power do I really need for my RV?
A: Most small to medium RVs need 2000-3000 watts for basic appliances like lights, refrigerator, and charging stations. Larger RVs with air conditioning, microwaves, and multiple electronics require 5000+ watts. Consider your peak power needs when several appliances start simultaneously.
Q: What’s the difference between inverter and conventional generators?
A: Inverter generators produce cleaner, more stable power that’s safe for sensitive electronics like laptops and phones. They’re also quieter and more fuel-efficient. Conventional generators provide raw power but can damage electronics and are louder. For RV use, inverter technology is generally preferred.
Q: Can I run my generator inside my RV?
A: Never run generators inside enclosed spaces like RVs, tents, or garages. Always operate them outdoors with proper ventilation. Carbon monoxide poisoning is extremely dangerous. Use generators at least 20 feet away from your RV with exhaust pointing away from living areas.
Q: How often do I need to maintain my generator?
A: Basic maintenance includes checking oil levels before each use, changing oil every 50-100 hours of operation, cleaning or replacing air filters regularly, and running the generator monthly for 30 minutes to keep it in good condition. Follow the manufacturer’s specific maintenance schedule.
Q: Are dual fuel generators worth the extra cost?
A: Dual fuel capability (gasoline and propane) adds flexibility and can save money during fuel shortages. Propane burns cleaner and stores longer than gasoline. However, dual fuel generators cost more upfront. Consider how often you’ll need this flexibility versus the added expense.
Choosing the right built-in RV generator is one of the most important decisions you’ll make for your RV adventures. Whether you’re looking for massive power for a large fifth wheel or quiet, reliable performance for weekend camping trips, the right generator ensures you never have to sacrifice comfort or convenience. From the massive DuroMax XP13000EH that can handle whole-home backup to the ultra-portable Pulsar 2300i perfect for small RVs, each of these generators offers unique advantages for different RV lifestyles. Remember to consider your power needs, portability requirements, budget, and safety features when making your decision. The best generator for you depends on your specific RV size, power requirements, and how you plan to use it. With any of these top-rated models, you’ll have reliable power wherever your travels take you.
