The best generator for RV in 2021: 12 top picks

Do you own an RV? If so, you may be concerned about your power usage and how to keep appliances running for long durations. 

One potential solution to your energy problems during road trips in your RV is RV generators. RV generators are appliances that can power electronics in your RV.

As a matter of fact, things could go haywire if you don’t own an RV generator. You could potentially run out of power on your field trip.

If you’re concerned about where to get the best RV inverter generators, look no further!

I’ve compiled a review of the twelve best RV generators out there.

Let’s get right into it.

RV generator VS tent camping generator 

RV generators and tent camping generators do have a lot of similarities. 

However, they are unique appliances with unique properties. Both have their own use cases and should be seen as identifiably different.

RV camping requires more power.

One of the most significant differences between these two is the power they need.

RV generators need a lot more power than tent camping generators or tailgating ones. This is because they usually have to power a lot more appliances. 

This includes ACs, refrigerators, and other power-heavy appliances. On the other hand, tent camping generators power smaller appliances.

Tent camping generators usually provide power for mobiles, laptops, bulbs, and other appliances. On the contrary, RV generators need to supply power to various appliances in the RV.

It depends on how much you use your RV. You could have refrigerators, microwaves, and other heavy appliances in it.

Noise level is less critical

Since RV’s are a lot more soundproof than camping tents, the noise level is not a huge issue for them.

You can have RV generators that produce more sound than tent camping generators.

This isn’t always a given, though. Some RV grounds have noise policies. So you need to be careful about using noisy RV generators in certain situations.

Benefit from RV generator box or a tray 

1. RV Generator Box

You can use an RV generator box to properly mount your generator. It also helps make sure that your generator is protected against external damage. 

I’ve found this product to be one of the best generator boxes on the market. It’s corrosion-resistant and highly dependable.

Moreover, it has anti-theft properties to keep your generator safe. 

You can lock it to keep your generator safe. Other than that, you can mount it on the A-frame of your RV. It’s a great, useful, and highly secure investment. You are also welcome to read this guide about running a generator during rainy weather.

2. RV Generator Slide Out Tray

 Another incredibly useful investment I’ve found is a generator slide out tray.

The RV generator slide out tray I recommend is this one from Amazon.

This is an amazing, high-quality slide-out tray meant for RV generators.

The best thing about an RV generator slide out tray is that it allows you to easily access your RV generator.

If you’re concerned about safety, don’t be!

This product provides you locking latches. These latches keep your RV generator steady and safe as you’re travelling. You won’t have to worry about the tray slipping under the generator.

You also won’t have to worry about the tray jamming, since it’s very resistant to jamming.

3. A tongue generator tray

Another useful component I’ve found is this tongue generator tray from Amazon.

You can use it to easily move your RV generators around.

When it comes to the installation, you may have to drill a bit.

Once that’s done, you can use it to move the heaviest of generators and other appliances.

What’s great about this product is that the installation components are all included. It’s suitable for most A-frames as well.

If your generators are heavy, this is the best tool you could want for moving them around easily.

How to choose the best RV generator 

Personally, I used this exact methodology to rank these generators.

I’ve analyzed many generators with this technique and I can vouch for it.

However, if you want to conduct your own research, there are some things you should pay attention to.

Let’s get to discussing them.

Step 1 – Consider the emissions ratings 

Emission ratings are the legal standards that governments impose with regard to emissions. They usually pertain to the amount of emissions that a device is allowed to emit into the atmosphere.

When picking a generator, do consider the emissions ratings. Check to see which generator conforms better to these standards.

Step 2 – Consider the power

The power output of the generator will be one of your most important concerns.

RVs can require a lot of power, and your generator needs to be able to provide that. You should be looking towards generators that provide you at least 3000 watts.

You’ll need even more power if you want to power your AC, refrigerator, and microwave. Therefore, it’s important that you thoroughly scout the market for the right generator.

Consider the appliances you’ll be powering. You’ll most probably have a few phones, laptops, kitchen appliances, and lighting equipment. 

Other than that, you’ll also have some heavy appliances like electric ovens.

You’ll have to calculate the amount of power you need by taking into account all these factors. If you don’t have an AC or a refrigerator, you could go with a smaller generator.

On the other hand, you need to be careful with your smaller appliances. Not all generators are ideal for smaller electronics like tablets and laptops.

If the quality of power is bad for smaller electronics, find another generator.

You have to be sure that your generator can power your appliances without draining the fuel. If you buy a generator that can’t power your RV on the road, you’ll face a ton of inconvenience.

Step 3 – Take the fuel efficiency into account 

You’ll be on the road constantly in an RV. You’ll want to make sure that the fuel efficiency of the generator is good.

That means you’ll want a generator that doesn’t run out of fuel too quickly. If you get an inconsistent generator, you’ll face refueling problems in remote areas.

Get a portable generator instead of an open-frame generator. Portable generators are more fuel-efficient than open-frame ones.

Step 4 – Think about the noise level  

Another important concern of yours should be the noise level of the RV generator.

Most RV generators are usually noisier than camping generators.  This isn’t always a problem, though. You’ll be on the road a lot and RVs are usually very sound-proof.

You could face problems when you’re in an RV camping ground. 

RV camping grounds usually have strict noise threshold requirements. You won’t be allowed to bring your generator outside if it is very noisy.

That’s why a lot of manufacturers are making relatively silent RV generators recently. Do consider the decibel level of the RV generator before you buy it. If it’s too noisy, it’s not a good choice.

Step 5 – Consider the type of fuel  

There are three main types of fuel that are used in RV generators. You’ll find diesel, propane, and gas being used commonly.

Let’s get into discussing each of these.

Gas: This is the most common type of fuel utilized in RV generators. Gas can vary in terms of price and isn’t cheap.

Diesel: The biggest disadvantage of diesel is that it is smellier than other fuel types. Other than that, diesel RV generators are very noisy as well.

However, they do offer a unique advantage. Diesel burns a lot cleaner than other fuel types. You can get more usage time from a tank of diesel than a tank of an alternate fuel.

Diesel RV generators are rather uncommon and not widely used.

Propane: This fuel type offers a much longer run time than both diesel and gas (per tank). The good news is that it is also gaining a lot of popularity in recent years.

How to install a generator on RV?

This section will teach you to properly install a portable RV generator on your RV.

Let’s get into it.

1. Determine where you want to install the generator on your RV

You’ll have to consider the build and type of your RV to determine where to install the generator. 

If you have a fifth-wheel RV trailer, check to see if there’s space in the front of the RV where you can mount it. In the event that there’s no extra compartment, mount it at the back.

You will have to be careful and see if the back of the RV can support the weight of the RV generator.

Finally, if you own a regular travel trailer, mount the generator behind the gas tanks of the RV. You’ll find them near the front of the RV.

2. Now, you need to make a structure for placing the generator

Your RV will have an A-frame near the front. Bolt the platform to the frame to make a working structure.

Alternatively, you could place a metal construction at a 90-degree angle to the RV bumper. You can secure this by using U-bolts. If you don’t want to use U-bolts, you can drill through the bumper.

Finally, if you’ve decided to mount the generator directly on the frame, secure it with U-bolts. Make sure that the metal channel is attached to at least 17-18 inches of the actual frame.

3. You can place the platform on the A-frame

You should place U-bolts across the mesh framework. This you should do if you prefer front mounting. 

If you’re looking to mount at the back, put fasteners through the mesh at the bottom of the platform. Then, tighten them around the metal channel structure.

4. Mount the RV generator on the final platform

You can now put the generator on the constructed platform. Now, all you have to do is to attach the generator to the base platform.

Check if your generator can be bolted to the platform. If so, great. If not, you’ll have to secure it some other way.

I’ve found that straps are helpful in this regard. You’ll have to attach the straps to the bottom of the platform structure. Then you’ll have to secure the top of the generator with the straps.

How to properly maintain an RV generator?

This section will address how you can maintain and care for your RV generator.

Let’s get right to it.

1. Do get your generator serviced at regular intervals

Your RV generator can suffer from lots of wear and tear over time.

Even if you keep it idle, the engine can wear, wires can get damaged, and lots of other issues can come up.

That’s why it’s important to keep getting your generator serviced at regular intervals. 

2. Don’t use old fuel

You should never be using old fuel in your RV generator.

I strongly recommend that you keep changing your fuel and replacing it with fresh fuel.

If you run your engine on old fuel, it can wear very quickly. That will lead to poor performance and other problems down the road.

3. Use/run your RV generator once every few weeks

Don’t keep your generator idle for long periods of time. You’ll get notified of potential issues before they become problematic.

Try to run it at least once a month so as to evaluate how it is running.

4. Store your RV generator properly

You need to store your RV generator in a place where it can’t be affected by external conditions.

Most RV generators can wear down rather quickly when exposed to moisture.

When you’re putting it away for long periods of time, do a few things to keep it safe. First, clean the casing of the generator. Check if the tank is full. You may also want to drain the generator lines.

5. Make sure you keep the battery clean

The battery lines need to be kept clean and hygienic. Check them regularly to see if they’re free of residue.

You may also want to disconnect the batteries if you don’t want to use the generator for a while.

6. Keep your RV generator well-lubricated

Your generator is an electrical appliance with several interactive components.

It needs to be oiled regularly. If you do keep it lubricated, the parts won’t clang and clatter as much. Therefore, your generator will output a lower amount of noise. 


What size generator is best for RV?

To be specific, a lot of RV generators offer power between 4500-8000 watts.

The right-size generator is the one that powers all the appliances you want.

If you have a smaller RV with not many appliances, a 2000-watt generator should be right. However, if your RV is large, you’ll need a lot more power.

A 3000-watt generator will be right for powering lots of smaller appliances and a few large ones.  On the other hand, if you have multiple heavy appliances, you’ll need more power.

If you want to power an AC, multiple ACs and refrigerators, go for a 4000-watt generator or more.

If you won’t be using an AC, a 2000-4500 watt generator will suit you.

How to charge an RV battery with the generator?

Before you charge your RV battery with a generator, you’ll need some safety measures.

I recommend that you get insulated gloves, goggles, and proper tools to work on your battery.

Now, once you’ve set up your materials, you can get down to business.

There are two ways to charge your battery with an RV generator.

One is to plug your RV into the generator. Once you do this, you can ever power your entire RV system. This includes appliances and electronics. However, this will slow your charging down.

The faster method is to use a portable charger with the generator and speed up the charging process.

How many watts generators do I need to run an RV AC?

In general, you’ll be able to run an RV AC on a 2000-4500 watt generator.

This does vary, however. It varies depending on the size and power requirements of the AC. It also varies depending on the number of ACs you want to power.

If your AC is small, you may be able to power it along with other appliances on a 2000-watt generator. However, if you want more power, you’ll have to look towards more powerful generators.

If you have a very powerful AC, you could look towards 3500-4000 watt generators as well. They’ll be able to power your AC and other appliances easily, for the most part.

Wrapping it up  

If you own an RV, an RV generator is one of the most important investments you’ll make. You just can’t afford to live without power on long road trips and journeys.

You’ll need a good RV generator to power your electronics on the road.

That’s why you need to be certain of your needs and requirements. You need to sure of how much power you need for your appliances and electronics.

I wrote this guide to help you pick the right RV generator for your needs. All of the RV generators I’ve listed are valuable in their own right.

Hopefully, by now, you’ll have a clear idea of what works for you and what you need.

All in all, be careful with regards to the quality of the generator and the fuel efficiency. Also make sure to pick the right combination of price and quality.

I wish you the best!
