Recap: Best RV Generators of 2021

Things to Look Out For Before Buying an RV Generator

Let’s look at some of the most important pre-purchase considerations you should be making before you purchase an RV generator.

First off, you need to figure out the purpose(s) for the generator:

  • Main power supply for multiple electronic devices and appliances?
  • Back up power supply or for emergency purposes?
  • How often will generator be used?
  • How much power is needed to run everything safely and efficiently?
  • What sort of features are important? Do you want remote start?
  • What kind of fuel, noise, weight specifications are important?
  • What is your budget?

Once you determine your needs and whether you want a bare-bones model to do the job efficiently or something a bit more advanced with more bells and whistles, it’s time to move forward to compare specific models.

Power Needs / Voltage Output / Usage

One of the most important factors is to determine the primary reason for purchasing the generator.

How many appliances and devices will be running at the same time? In addition to basic power and small appliances, how many electronics and cell phones are involved? If you use the RV on a closer to full-time basis, is a heavier duty generator a better choice? Appliances like air conditioners, fridges, and others are going to take up a lot of power in your motorhome or travel trailer.

Be sure to factor in whether you will be using the power to charge RV batteries, which will take a considerable amount of energy on its own.

There are also RV generators that can connect with others to produce twice as much power. Is that an important feature for you?

Make sure the generator can handle all the power demands you need for extended periods of time.


It’s important to consider the size and weight of the generator to make sure that it fits properly into the RV. While it needs proper storage, remember that it needs to be accessible for maintenance and repairs, if necessary.

If you will be moving the generator from one location to the next, you probably want to get a model that’s lightweight and small enough to carry by yourself and fit into your vehicle.

Keep in mind that while portable, some of the generators can weigh around 100 pounds. If you have mobility limitations, be sure to do your homework in terms of generator size and what you will realistically be able to handle.

Fuel Type & Consumption

Some fuels burn “cleaner” than others (i.e.; propane). While propane generators may be cleaner, it tends to run at about 10% less efficiency than gas or diesel. If environmental issues are important to you, keep in mind the fuel source for your generator. Perhaps a dual fuel model is for you. Also, is your selection based on the ability to tap into larger fuel sources such as a more permanent supply like a propane tank? Make sure to take that into account as well.

Here are the main fuel types:

  • Diesel powered RV generators – a good choice if your RV already runs on diesel
  • Gas powered RV generators – very budget friendly, easy to find
  • Propane powered RV generators – more environmentally friendly option, less emissions

Brand Name / Reputation

You may be sold on a name brand that has a ton of positive user reviews. Make your decision based more on the long-term trend of durability and sustainability of your generator (and how you are going to use it) regardless of the manufacturer.

Noise Level

The decibel levels can be a huge consideration if you plan to use the generator on camping trips or where there may be a lot of people nearby. It’s always a good idea to be a considerate neighbor.


Last but not least, take the time to compare features and benefits to price.

You want a safe, dependable generator for a reasonable price. Look for models with outage and surge protectors to avoid potential damage to your electronics and devices.

Weigh the cost of your investment over the long haul and if what you are getting justifies the up-front cost. If you know you are going to use the generator a lot, a higher price up-front may mean less maintenance over the long haul. Will you use a more costly generator enough to validate the purchase price?
