RVs can bring a whole lot of fun to you, your family, and friends, but what happens when you run out of power? You can’t depend on the basic battery of your RV to keep all your electronics up and running for days on end, so what do you do? Well, you get an RV generator of course!

RV generators are your safe bet when it comes to outdoor life, they help sustain the various appliances and gadgets during your trips so you can enjoy your time without worrying it’ll all come crashing down!

Types of RV Generators

RV generators aren’t all the same. In fact, there are three different types according to the fuel used to operate them. Each one has its advantages and disadvantages which we’ll be discussing so that you can choose the most suitable generator.

Gas-powered Generators

These generators run on gasoline which is probably the most accessible and readily available fuel, so it’s the more convenient choice. Gas is also the least costly out of the three fuel types.

While it’s easy to refill this kind of generator, you have to be careful with storing and transporting gas as it’s highly flammable. Additionally, you should avoid leaving gas in the tank over long periods of time as it can clog the carb.

Unfortunately, gasoline has a short shelf life due to the presence of impurities, which also affect its burning making it unclean and harmful.

Propane powered Generators

Generators operating on propane aren’t as powerful as ones running on gas or diesel, the lower levels of power require you to constantly keep an eye on your consumption and plan it out extra carefully.

On the upside, propane as a fuel is a clean-burning power source that gives off less harmful emissions. This means less damage to the generator and less maintenance work for you. It has a long shelf life allowing you to keep it from one summer to the next. Propane powered generators are also of a cheaper price.

Diesel-powered Generators

If you’re looking for the highest amount of power production, the diesel-powered generators are exactly that. They offer a cleaner burning ability compared to generators utilizing gasoline. Also, you can store diesel safely.

If your vehicle already runs on diesel, it’d be a smart choice to also use a diesel-powered generator considering you’ll be feeding them a single fuel.

The catch with this type of generators is that they are built with heavier and bulkier components, which translates into extra weight added to your vehicle. They also tend to produce more noise than other kinds of generators.

What to Look for in an RV Generator?

Jumping into buying an RV generator isn’t the ideal approach if you want to find the best RV generator. Instead, you should first consider a few points to really get an idea of what will work better for your needs.

Power Output

The one vital factor in choosing the best RV generator is how much power it produces. You need to make sure your generator supplies adequate power to operate all your electronic devices without completely draining the available fuel reserve. You also don’t want excessive power capacity that costs too much and exceeds your budget.

If you lean towards small trips, you’d probably be fine running a 1000 watt generator to power small devices such as phones and lights. However, if you want a full-on motor-home experience, a generator with at least 3000 watts of power is what you need to comfortably run heavy demanding appliances such as that 15,000 BTU air conditioner along with other tools.

Portability

The decision between a portable or a permanent unit is something you should get over with to better decide what generator is best for you. Permanent generators are attached to your vehicle at all times, which is why most people prefer the portable type as it offers way more versatility in cases of power outages as well as tailgating on top of the intended RV usage.

To enhance portability, generators are generally built not too heavy or bulky so that you can easily move and transport them single-handedly if the need arises. Sturdy wheels and adjustable handles are also a great plus when it comes to handling portable generators.

While it’s true that portability tends to cut down on power output, the issue can be resolved simply using the parallel capability. This allows you to connect two generators together, operating as one unit delivering double the power.

Noise Level

Too much noise can definitely ruin what would otherwise be a perfect getaway, not only for you but for those surrounding you as well. For the sake of avoiding such inconvenience, you should take into account the noise level your generator produces, typically measured in dBA (decibels).

Multiple brands are noticing this problem and actually worked on providing muffling solutions where generators produce less than 60 dbA noise level. You should be just fine with such noise levels that allow you to have normal conversations comfortably, frustration and distraction free.

Note that the more power you seek, the louder the generator will get. It’s unfortunately bound to happen due to increased load.

Fuel Consumption

Something that shouldn’t escape your attention is the fuel consumption as well as its efficiency.

What you want here, is generators featuring certain advanced technologies that enable them to adjust their engine speed according to the power demand. This means that the engine automatically reduces its speed when a few light appliances are connected, thus, minimizing fuel consumption. You want your engine running full-throttle only when it’s necessary.

Such a smart feature lets you better plan your fueling schedule, how much to stock, and how often you need to refill.

Convenience

Features to enhance your interface and facilitate the operating of your generator are always welcomed. From displays that allow monitoring consumption statistics to wireless remote start and low-oil shutdown safety feature, all are useful additions for optimum performance.
