How to Choose Best RV Generators

Selecting the right generator is crucial for maximizing your RV freedom, ensuring you have the necessary power to run your essential amenities comfortably. A generator provides AC power for everything from lights and charging stations to air conditioning and kitchen appliances when you’re off the grid. Choosing the wrong unit can lead to insufficient power, excessive noise, or unnecessary weight. Since you are specifically considering best dual-fuel inverter generators, you must balance capacity, fuel type, and noise.

Power Output (Running & Starting Watts)

The most critical factor is the power needed to start your heaviest appliance (usually the AC unit) and then keep everything running simultaneously. The starting wattage is a temporary surge, while running wattage is the sustained power output. You need enough running watts to cover your total continuous load and enough surge watts to handle the AC start-up. Always calculate your total load, then look for a generator that exceeds both requirements.

Noise Level (Decibels)

Noise level, measured in decibels (dBA), is paramount when camping. Many campgrounds enforce strict noise limits (often 60 dBA or less). Inverter generators are dramatically quieter (50–65 dBA) than traditional open-frame models (70–80 dBA). To evaluate, check the dBA rating at a specific load (e.g., 50% load from 23 feet) and compare it against campground rules to ensure compliance and courtesy.

Fuel Type and Flexibility

Generators typically run on gasoline, propane (LPG), or both (dual fuel). Gasoline offers the highest power density, while propane provides longer storage life and can be used with the RV’s existing LP tanks, offering great convenience. Dual-fuel generators give you ultimate flexibility in an emergency or when one fuel source is unavailable. For maximum convenience and power, many RV owners prefer best inverter generators for RV use with dual-fuel capability.

Portability and Size

The generator must be easily transportable and fit securely in your RV’s storage compartment or on a hitch carrier. Weight is a major consideration; lighter units (under 60 lbs) are easier to handle but have lower wattage. Larger units may require a wheel and handle kit. Assess your physical comfort with the weight and the available space on your rig before committing to a purchase.

Inverter vs. Conventional Technology

Inverter generators produce clean, stable power (low Total Harmonic Distortion or THD), making them safe for sensitive electronics like laptops and TVs. Conventional generators are often louder, heavier, and produce “dirtier” power, which can damage sensitive devices. Given the amount of modern tech in an RV, choosing an inverter generator is nearly always the better choice for safety and efficiency. This is particularly true if you are considering a unit for home use as well; in that case, check out the best inverter generator for home backup.

Maintaining Your Best RV Generators

Proper maintenance ensures the longevity and reliable performance of your generator, which is crucial for power when you need it most. Routine checks, such as monitoring oil levels and keeping the air filter clean, prevent costly breakdowns. A vital mistake many users make is neglecting the fuel system during storage. Gasoline degrades quickly, gumming up the carburetor. To avoid this, always use a fuel stabilizer before storing the unit, or if possible, run the unit dry by using the fuel shutoff feature (if equipped) until the engine stalls.

Safety should also be a constant priority. Always operate your generator outdoors and away from open windows and doors to prevent carbon monoxide poisoning, even if it has a CO sensor. Never run the unit inside an enclosed RV compartment or under the RV itself. Regular inspection of the spark plug, checking for loose connections, and adhering to the manufacturer’s maintenance schedule for oil changes will keep your unit in top working condition for years of reliable travel. For an excellent overview of inverter generator care, you can read more at Electric Generators Direct’s guide.

How to Use Best RV Generators

Here are the practical steps and best practices for using your RV generator safely and effectively on your trip.

  1. Setup and Safety: Before starting, place the generator on a level, stable surface at least 15–20 feet away from the RV, doors, windows, and vents. Check oil and fuel levels. If you are using propane, ensure the hose is securely connected to the generator and the LP source.
  2. Starting & Connection: Turn the fuel valve on (if applicable) and engage the choke. Use the recoil or electric start switch to fire up the engine. Once the engine is running smoothly, disengage the choke. Plug your RV’s main shore power cord directly into the generator’s RV-ready TT-30R outlet (using an adapter if necessary).
  3. Core Usage & Best Practices: Always power up your appliances sequentially, starting with the highest-draw item (like the AC unit) first. Use the Eco-Mode or Economy Mode feature (if available) to adjust the engine speed automatically based on the load, which conserves fuel and reduces noise output.
  4. Shutdown & Storage: Before shutting down, turn off all connected appliances. If the unit is gasoline-fueled, engage the fuel shutoff valve (if available) to let the carburetor run dry. If not, run the unit until the fuel tank is nearly empty, then turn the ignition off. Allow the generator to cool completely before covering or storing it.

Frequently Asked Questions

What size generator do I need for my RV’s air conditioner?

For most RVs, a generator with a running wattage of 3,000 to 4,000 watts is sufficient to power a single 13,500 BTU or 15,000 BTU air conditioner, along with some lights and a microwave. Always check the AC unit’s label for the exact starting (surge) wattage requirement, as this is the most demanding part of the load.

Are inverter generators worth the extra cost for RV use?

Yes, for RV use, inverter generators are almost always worth the extra cost. They are significantly quieter, produce cleaner power safe for sensitive electronics, and are more fuel-efficient than traditional generators. Their lightweight and compact design also makes them far easier to store and transport on the road.

Can I run my generator in the rain?

You should never run a generator exposed to direct rain or wet conditions, as moisture can cause electrical shorts and create a serious safety hazard. If you need to operate it in wet weather, you must use an approved generator tent or canopy to shield the unit, ensuring that proper ventilation and exhaust clearance are maintained at all times.

How long will Best RV Generators run on a full tank?

Run time varies greatly depending on the tank size, the load being placed on the unit, and whether it has an Eco-Mode. Small inverters (2000W class) typically run 4–9 hours on a small tank at a 25% load. Larger 4000-5000W inverters and conventional generators can run from 7 to 14 hours at half load due to larger fuel tanks.

Do all Best RV Generators come with a TT-30R outlet?
