Types of Generators for RVs


Diesel generators are best if your recreational vehicle runs on diesel fuel. This enables you to use a single fuel source for both your generator and your camper. The best diesel generator for RVs also produces more power than propane and is safer to store because it’s nonexplosive.

Liquid Propane

The main benefit of a liquid propane generator is that it is environmentally friendly. The best propane generator for RVs produces cleaner emissions and has a longer shelf life than other types of generators. However, the run time of the generator is dictated by the size of your propane tank. Also, it doesn’t have as much power output compared to gas or diesel generators.


The third type of generator is gasoline powered. Some RVers like them because gasoline is easy to procure, and it’s not (usually) very expensive. But there are several drawbacks. First, gasoline is highly flammable, so you need to take special care when handling it. Also, gasoline’s shelf life isn’t as long as other fuel sources, and it burns a lot faster than diesel, so fuel efficiency is an issue.

What to Consider When Buying an RV Generator

Power Output

One of the most important features to consider is a generator’s power output. It needs to have the ability to power all your electronics and appliances. Make sure to estimate the amount of power you think you will need to run a variety of items. For example, the best generator to power an RV air conditioner will have enough wattage to accommodate your particular needs.

Size and Portability

Look for a generator that is large enough to provide the power that you require but isn’t too bulky. A running generator should generally be placed at least 10 feet away from sleeping quarters to reduce carbon monoxide risks, so portability is critical in the RV generator world. While on the go, measure your camper to make sure it can be stored in the allotted space. Smaller units are more portable and easier to move from one area to another. The best portable generators for RVs are very versatile and can be used for RVing as well as tailgating, or if you have a power outage at home. 

Noise Level

Look for the quietest generator you can find. Some RV generators are noisier than others, so pay attention to the decibel ratings from the manufacturer, but always read user reports for confirmation. You want a camping generator that does the job but doesn’t keep you up at night because it’s too loud. Many companies specifically produce generators that can run in a quiet mode when in operation. This is important because many national parks and private campgrounds have noise regulations.

Fuel Consumption

Think about how often you need to add fuel to the generator. The best RV generator should last for several hours without refueling. Some products have an eco-mode that reduces the amount of fuel that is burned. Plus, you have to consider the type of fuel it uses and whether it’s available in your location or along your route. 

Generators for RVs Pricing

They aren’t cheap. You’re going to be spending between $500 and $3,000 in some cases. Choose accordingly.


You’ve got questions. The Drive has answers.

Q: What type of fuel is best for a generator?

There are many options available, including gasoline, diesel, propane, and natural gas, and they all have advantages and disadvantages. Gasoline is widely available but doesn’t last long in storage. Diesel generators are efficient but can also be expensive. Propane doesn’t degrade when it is stored and is a bit cleaner than gasoline and diesel, but like a lot of fuels, storage can be dangerous if you aren’t careful.

Q: How much power do I need with an RV generator?

Different RVs have different power requirements. Some appliances, like air conditioners, use more energy than others, such as TVs. It’s best to get the maximum wattage ratings of the generator and compare it to the total requirements for your particular RV.

Q: How do I maintain an RV generator?

It’s best to consult the service manual for your particular generator. Generally, they should run for at least an hour every month, and the oil should be checked regularly. The filter, oil, and air cleaner will also need to be changed according to the manufacturer’s instructions.
