The Ultimate Guide to Choosing the Right RV Generator for Your Adventures

Whether you're a weekend warrior or a full-time road warrior, having the right RV generator can make or break your adventure. From powering your morning coffee to keeping the AC running on a hot desert night, a reliable generator ensures you’re never left in the dark—literally. But with so many options out there, how do you choose the right one? This guide breaks it down for you, so you can hit the road with confidence.

Why You Need an RV Generator

A generator in your RV is your lifeline to comfort and convenience when shore power isn’t available. It powers your:

Air conditioner

Microwave

Refrigerator

Electronics and charging devices

Lights and fans

Water heater and pumps

Without a dependable generator, boondocking or off-grid camping becomes a lot less comfortable—and a lot more limiting.

Types of RV Generators

There are several types of generators to choose from, each suited for different needs:

1. Portable Generators

Ideal for occasional users or those who want flexibility. They're affordable, easy to maintain, and can be used outside of RVing too (like during home outages or tailgates).

 Pros:

Cost-effective

Lightweight

Versatile use

 Cons:

Noisy (unless inverter style)

Require manual setup

2. Inverter Generators

Known for quiet operation and fuel efficiency, inverter generators are perfect for sensitive electronics and eco-conscious travelers.

 Pros:

Quiet

Clean power

Fuel-efficient

 Cons:

Higher upfront cost

Lower power output (unless paralleled)

3. Built-In Generators

If you have a Class A or Class C RV, you might already have one. These integrate seamlessly into your RV’s power system and start with the push of a button.

 Pros:

Convenient

High power output

Runs off RV’s fuel source

 Cons:

Expensive to repair

Adds weight

What to Consider When Choosing an RV Generator

Before making your purchase, factor in the following:

1. Power Output (Wattage)

Estimate your total wattage needs. Add up the watts required by appliances you plan to run simultaneously. A 3,000-watt generator is usually sufficient for most RVs.

Tip: Don’t forget about surge wattage—many appliances need extra power to start up.

2. Fuel Type

Common fuels include:

Gasoline: Easy to find but burns fast.

Diesel: Efficient, especially for diesel RVs.

Propane: Clean-burning, but less energy-dense.

Dual-Fuel: Offers flexibility for different fuels.

3. Noise Level

Noise is a big deal, especially in campgrounds. Look for a generator rated below 60 dB at a quarter load—quiet enough for conversation.

4. Portability

Will you move the generator around, or will it stay mounted in your RV? Portables are lighter and easier to store, but built-ins are plug-and-play.

5. Budget

Generators range from $400 to over $5,000. Portable and inverter generators are more budget-friendly, while built-in options offer premium features at a higher price.

Top RV Generator Brands to Consider

Honda: Known for quiet, reliable inverter generators.

Champion: Excellent balance of price and performance.

Cummins Onan: The gold standard for built-in RV generators.

Westinghouse: Solid budget-friendly options with advanced features.

Bonus Tips for RV Generator Use

Always perform regular maintenance (oil changes, air filter cleaning).

Store fuel safely and away from heat sources.

Use a surge protector to safeguard your RV’s electrical system.

Let the generator run under load regularly to prevent carbon buildup.

Final Thoughts

Choosing the right RV generator boils down to understanding your power needs, lifestyle, and budget. Whether you prefer stealthy nights in the forest or desert sunsets far from hookups, the right generator turns your RV into a true home on wheels. So pick smart, pack up, and power your next adventure like a pro!
