Buying and Using an RV Generator

Buying and using an RV generator may be at the top of your to do list. If you own a motorhome, it’s likely you already have an onboard generator. That said, those who own fifth wheels and bumper pulls probably don’t have such a lovely convenience. This is unfortunate for these individuals.

You see, a generator is what makes it possible for RVers to have sufficient electricity when camping off-grid. Considering this ability is one of the main reasons many people invest in RVs, those who don’t have a generator already might want to look into adding one to their camping setup.

Those of you who fit into this category may be wondering where to begin on your hunt for the perfect generator, and what to expect once you have one in hand. Lucky for you, this article addresses this very thing.

Read on to learn the ins and outs of buying and using your very first RV generator.

What to Look For

Let’s begin by discussing what to look for in a portable RV generator. Below are the main attributes to consider. Knowing what you need in each of these areas will make your shopping experience go much more smoothly.

Power Output

First and foremost, you will need to consider your needs when it comes to power output. If all you plan to do is recharge your house battery once in a while, a lower power model (2000–2200 watt) will be sufficient. On the other hand, those who wish to run an air conditioner unit, run many things at once, or use a microwave will need at least 3500–4000 watts, and could want for even more.

Outlet Types

In addition to power output—and going hand in hand with that particular attribute—are the outlet types offered by the generator in question. Lower power generators will have a few 120-volt AC outlets and could possibly include some USB ports as well. Higher power generators that offer at least 4000 watts of power may include other types of outlets, including a 30-amp RV outlet, making it super easy to plug in.

Fuel Needs

The most common type of portable generator is the gas-powered generator. That said, there are also diesel-powered portable generators, as well as the least popular propane options. All have pros and cons.

Gas-powered units are cheaper up front than the other options. They run quieter than their diesel counterparts, and fuel is very easy to find and refill quickly. Additionally, these units are very easy to find in almost any RV store, as well as many hardware stores and other such shopping places.

On the other hand, diesel generators require much less maintenance than gas options thanks to their lack of carburetors or spark plugs. They are also very fuel efficient, something that will be extremely helpful to those who use their unit often. Diesel generators are a bit trickier to find, but not unreasonably so.

Finally, propane burns cleaner than the other two fuel types, making this type of generator a greener alternative. That said, carrying and refilling propane is much more of a hassle. And sometimes, finding a propane generator can seem impossible. In most cases, we don’t think the search is really worthwhile, and recommend going with gas or diesel instead.

Fuel Tank Capacity and Run Time

If you go with a gas- or diesel-powered unit, you will also want to consider the tank capacity. Obviously, the more fuel your tank can hold, the longer your generator will be able to run without a refill. If you’ll run the generator for long periods of time on a regular basis, a larger fuel tank is a must-have.

In addition to tank capacity, fuel efficiency will also affect the run time of your generator. Therefore, this is something you’ll want to check for in the specifications of your generator before purchasing. Checking reviews is also a good idea in order to a get a realistic idea of what the run time might be.

With Inverter versus Without

As you are researching portable generators, you’ll likely notice that you have the choice of an inverter-equipped unit or one without. Generally, the inverter units are more expensive than others. However, we feel that the pros of these inverter generators far outweighs the cons. They are quieter, more efficient, and much lighter-weight, making them more portable.

All of these things are important to the RVer who must travel with their generator and use it in areas where other people may be gathered and wish for a peaceful camping experience.

Power Startup

You may also notice that you have the option of an electric startup. While it certainly is cheaper to skip this option, many people claim the power startup option is well worth the extra investment. This will allow you to get your generator going quickly and easily every time, with very little effort.

The other option is to pull a recoil cord, lawnmower style, which can be a huge hassle and doesn’t always give immediate results.

Noise Level

Some generators are definitely noisier than others. You can check the noise level in the specifications of any unit. However, as a general rule it is good to remember the two things we mentioned above.

1. Diesel generators are quite loud, while gas-powered options tend to be quieter.

2. Generators with an inverter are leaps and bounds quieter than those without.

Using Your Generator

For the most part, using your generator is relatively easy. That said, there are a few rules of thumb you will definitely want to keep in mind:

Rule #1: Follow the Instructions Carefully

The very first thing you should do upon pulling your generator out of the box is carefully read the instructions. Once you’ve read them, follow them as closely as possible. This means performing any “breaking-in” tasks, as well as staying on top of regular maintenance. Doing this will ensure your generator lasts as long as possible.

Rule #2: Never Run the Generator Indoors

It might be tempting to keep your generator in a cargo bay in order to avoid theft. However, this is never ever a good idea. The generator should always be run outside and several feet away from the RV. This is for your safety and should be taken seriously.

Rule #3: Observe Quiet Hours and be Courteous

When camping near other people, make sure you are being courteous. Keep in mind that even the quietest generator still makes noise and should be shut off during quiet hours. If your camping area doesn’t have set quiet hours, a good rule to make for yourself is to turn the generator off by 10pm and keep it off until at least 8am.
