Types of RV Generators
Other than the solar option, an RV could have two types of generators: built-in and portable.
Built-in RV Generators
If you have a large Class A or C motorhome or RV, a built-in generator is a great option. They are quite powerful. Models that come pre-installed in large RVs can generate up to 12,000 watts, letting you run all your appliances and AC at once. Thanks to their size, built-ins also stay quieter than portable options. You won’t get that loud droning sound outside your window.
Another perk is simplified maintenance. Built-in generators are fueled straight from your vehicle’s tank, so no dealing with refilling portable cans. They start automatically when you start the vehicles and many even adjust automatically for high altitudes, like in mountain roads.
Of course, built-ins do have some drawbacks. Accessing them for repairs can mean major work that requires a service technician. You also need to take gas exhaust precautions, like running a CO detector, since fumes can creep inside the RV.
Portable RV Generators
Portable generators are the right choice for smaller RVs, like Class B vans or towable campers, that don’t have their own onboard fuel source. They sit outside the RV on the ground while in use. This means they are further away from people inside the RV, which is safer. You can also easily refuel and service a portable generator since it’s not enclosed in the RV.
However, the smaller size of portable generators limits the total power output available. You also need to set them up when you arrive at your campsite. When traveling, portable generators need to be properly stored inside the RV too.
There is a wide range of portable generator sizes to choose from. Very small models around 150 watts can run a few lights or charge devices. Larger portable generators up to 8,000+ watts have power for all of an RV’s needs.
Choosing The Best RV Generator For Camping: Criteria
To choose the best RV generators, you must consider some criteria. We’ve discussed them in detail for your better understanding.
Capacity / Power Output
The power capacity of a generator refers to how many amps of power it can provide at once. You’ll need to calculate the total amps required by all the appliances you want to use together.
For example, if one appliance needs 20 amps and another needs 15 amps, you’ll need a generator that can output at least 35 amps. However, if you’ll only run one appliance at a time, the higher single need of 20 amps is sufficient.
You’ll also need to match the generator’s voltage to what your RV and appliances require. Most RVs use 12-volt DC systems, but some items, like microwaves, need 120-volt AC. Be sure your generator can supply the highest voltage you need.
It’s also important to factor in your planned load. Suppose you want to run several appliances totaling 2,348 watts simultaneously. You’ll need a generator capable of at least that output.
And to avoid overworking the generator, add about 20% extra capacity above your maximum planned load. Using the example above, a 3,200-watt generator would provide a comfortable safety margin. Leave some extra power capacity if you may add more high-wattage items in the future.
Choosing a generator with sufficient capacity, correct voltage, and a buffer above your anticipated loads will ensure you have reliable power for all your camping activities and appliances.
Fuel Type
RV generator types and the fuel they use are:
- Built-in RV generators: Gasoline, diesel, or propane
- Portable generators: Dual-fuel option that can switch between propane and gasoline
So, it’s obvious that there are three different fueling options available for these generators:
Diesel RV generators
Diesel generators are a great choice if you already have a diesel-powered RV or truck. They provide reliable power and are very durable since diesel engines last a long time with basic maintenance.
The fuel type gives you more power from a smaller engine size compared to gas generators. It also burns cleaner than gas. However, diesel does cost more per gallon than gas or propane.
Propane RV generators
Many RVers choose propane generators because propane is available everywhere. It produces about 10% less power than gasoline. However, at around 90,000 BTUs per gallon, the power output is more than decent.
Propane has a really long shelf life, so your fuel will still be good even if you only use the generator once a year. This is better than gas, which can go bad if not used regularly.
Gasoline RV generators
Gasoline generators are simple because gas is found everywhere so filling up is no problem. Additionally, some gas generators can pull fuel directly from an RV’s main gas tank, which is handy.
While gas is also usually cheaper than diesel, it does burn through faster when running a generator. Also, it doesn’t last as long as propane in the tank if the generator isn’t used often.
Fuel Consumption
You want your generator to run for as long as possible between fill-ups. So, you must consider these few key factors that determine how efficiently a generator will use its fuel.
The first thing to look at is the size of the generator. A smaller generator with lower power output will use less fuel than a larger one. For example, a 2000-watt portable generator can run for 6-8 hours on a single gallon of gas. However, a 5000-watt standby generator may burn through a gallon every hour.
As well as size, pay attention to the load on the generator. Running it at full capacity means it won’t be as efficient as running it at a lower load. The tasks it’s powering, like air conditioning or battery charging, affect how much fuel it consumes.
Weather itself can impact fuel efficiency. Extreme temperatures or humidity cause generators to work harder and use more gas.
Handy Features
Every camper has different needs, so think about what’s most important for your trips. You can consider these handy features on top of the basic functions of your RV generator:
Look for a generator that has its own enclosed box. These are called inverter generators and they work great for RVs. The enclosure makes the generator much quieter than larger, open types. It also keeps the generator protected for traveling.
Check if it has parallel jacks. These special ports let you connect multiple generators together to produce more power. This can be handy if you need to run bigger things, like an air conditioner.
You don’t want a generator with a really small gas tank. That means you’ll be refilling it very often whenever you use it. A larger fuel tank lets the generator run for longer before needing more gasoline.
Safety features are also key. Things like circuit breakers and automatic shut offs help prevent accidents. See if it comes with useful accessories like a muffler to reduce noise even more.
Noise and Emission
Noise is an obvious factor since you’ll want your generator to run quietly without disrupting others camping near you. Generator noise is measured in decibels, and most RV generators fall in the 65-75 dB range. Quieter options under 70 dB are best for camping. The enclosed inverter generators tend to be the quietest option.

Emissions are important for the environment and safety. RV generator exhaust contains carbon monoxide, so proper ventilation is a must. Make sure to get an “EVAP certified” generator if your RV has a built-in system.
These special generators capture exhaust gasses to burn them fully and meet EPA regulations. Towable RVs need all certified EVAP components like hoses, fittings, and a carbon canister to be compliant with laws and safe on the road.
Price
Budgeting is an important factor in choosing an RV generator. Generators come in a wide range of prices from around $500 for smaller basic models all the way up to $5,000 or more for high-end heavy duty units. You have to balance how much you can afford to spend with the size and power of the generator you’ll need.
Don’t forget that an RV generator is a major purchase, so be sure to do your research. Take time to determine what electronics and appliances you want to power in your RV. Then, compare generator options and their available wattage or running watts. It will ensure you don’t get a generator that’s too small for your needs.
Final Thoughts
Choosing the right RV generator will make your camping trips much more enjoyable. Look for a generator that is quiet, fuel efficient, and can power what you need, like a small fridge or TV.
Also think about getting one that will last for years so you don’t have to worry about it when out in remote areas.
