The Best RV Generator: A Comprehensive Guide

There are large varieties of RV generators out there, but the great question is; how can you find the perfect one that meets your needs without spending a fortune? The demand for RV generators has increased in recent years. The devices can come in handy when you are outdoors camping or when the power grid is down at home.

In this article, we are going to guide you on buying an RV generator that will power your appliances without busting your budget. We are also going to answer some of the most common questions about these devices as well as how to maintain.

Things to consider when buying a generator for your RV

Before buying an RV generator, there are some factors you need to keep in mind. These factors will help you make an informed decision. Below are some of these factors discussed in details:

Power out

Many generator users usually associate the size of the generator with its power output. It is a good idea to consider the generator’s power output before buying it. You need to be sure that it will power all of your appliances without consuming too much fuel. If your RV has a lot of cool gadgets, it is even more important that you get a generator that will be able to sustain your lifestyle. The best starting point is determining how much power you are going to need. This will be made easy if you can take into account every electronic device that requires power in your RV. The general rule of thumb is getting a portable generator with more than 2000 watts.

Noise level

As far as the noise is concerned, the bigger and powerful your generator is the louder is likely to be. However that is not necessary these days, with the advancement in technology, there are many portable generators that function with minimal noise levels between 50 to 60 decibels, which is quite an improvement from the previous models.

Also, while many people might not know this, the fuel you use in your generator will influence its noise output. Diesel and gas-powered generators tend to be louder than their propane-powered counterparts. But inverter options will help you reduce the noise.

Assuming you want a quiet generator, you should get one for your RV with a tolerable noise output. Generally, if quietness is what you are after, then you should choose a generator that produces less than 65 decibels.

Note that if you are planning to go on a forest camping or any other camping ground, you are likely to be slapped with a noise restriction to about 60 decibels at 50 feet.

Alternatively, to avoid feuds with the locals or authorities, simply go for an inverter generator. These types of generators use special advanced technology that allows the engine to work using varying speed.  They also use less fuel, which is why they make a minimal sound. 

Fuel consumption

If you don’t do your homework well, you will end up with an RV generator that needs re-fueling every thirty minutes. You will end up spending a lot of money on fuel as well as time re-fueling. Those are not the only problems if you are out in the woods with your RV; chances are the nearest gas station is halfway around the earth. So if you generator run down the fuel every other hour, getting more might be a huge problem.

Today, you can find portable generators that can function up to 5 hours on just 2 gallons of fuel. Note that the more powerful your generator, the more fuel it will need. Also, open frame generators will burn fuel at a faster rate than other portable models.

To avoid being stuck in the middle of nowhere without power, you need to be rational. Going for a bigger, more powerful generator for your RV can be a wise move, but it is costly. However, buying two portable generators to run parallel to each other is a more cost-effective solution.

When buying an RV generator, choose the one that balances providing the most power out with least fuel usage.

Maintenance

A perfect RV generator is one that requires minimal maintenance; otherwise, you risk getting stranded right in the middle of your fun adventure. A generator that requires constant maintenance means burning more cash.

Get a portable generator that is reliable and will run for hours without any disturbances. Generally, diesel-powered tend to require minimal maintenance than their gas-powered counterparts.

Types of fuel RV portable generators use mainly four types of fuels; natural gas, propane, diesel, and gasoline. As you can imagine, different fuel will mean different performance. If you don’t want smelly fumes to invade your outdoor adventure, then your best bet is a propane-powered generator. It burns cleanest of all generators, followed by diesel, and then gasoline. Besides, propane is the most environmentally friendly fuel than others, and the easiest to carry

Maintenance of your RV generator

 Maintaining your RV generator makes total sense. After all, you have just spent a lot of your money on it, and you want it last for long. Here are a few maintenance tips for your machine.

  • Keep track of the hour meter

The hour meter keeps the track of the time your RV generator has been running. All RV generators have one. The benefit of checking this meter is so that you can know when to change the generator’s oil.

  • Change the oil, filters, and fluids of your generator

Generally, you are supposed to change the oil in your RV generator after fifty hours of running and every hundred-and-fifty hours after the first change. You should also change the filters when changing the oil, as well as the topping the coolant level.

  • Run your generator frequently

You need to use your RV generator frequently to ensure things run smoothly. If are storing your generator for future use, at least run it every 3 to 4 weeks to prevent the fuel from sticking up the generator.

  • Don’t remove the covers

Never remove the front cover or any cover from your RV generator while it is still running. The covers are designed to enhance airflow in the engine.

Common questions answered

Q: how much power should an RV generator produce?

A: First check out your appliances in your RV and single out those that use 120 volts. Add the number of voltages to get an idea of the minimum wattage requirement. Remember too much power will blow the circuits in your RV, and too little won’t be able to sustain you.

Q: Gasoline or Propane?

A: While these two fuels are the most popular among the RVers, they both have their own good and bad sides. Go through each advantage and disadvantage and see which fuel suits your lifestyle, however for most people we highly recommend gasoline engines at least when starting out
