One of the most important things to look into when trying to find the greatest is the engine. This will give you a good idea as to how reliable and powerful each one is.

We recommend models that use a 4-stroke, 224 OHV engine that can produce up to 4250 watts. This should give you enough power for your recreational vehicle.

If you want the ability to increase your power output, you’ll need to find a generator that is parallel ready. This will let you connect one or two more generators. This type of design can be tremendously beneficial in a variety of situations. Take a look at how many parallel ports are on each one.

Noise Level


The fact is that the very best will be powerful but quiet. You’ll need to find out what the noise level is for each one before making a final decision.

It is best to purchase a generator that won’t produce more than 68 decibels of noise. This will ensure that you get what you need without having to deal with more noise than necessary. It will also reduce the chances of bothering anyone else who might be in the general area.



Take a close look at the various outlets that each generator offers. You should have two basic 120-volt, 20-amp household outlets. Any model that is designed for use with an RV will also have a TT-30R outlet. This will let you power your recreational vehicle with no issues whatsoever.

You’ll find that most modern inverter generators will also be equipped with one or two USB 5-volt ports. This will allow you to keep your smartphone, laptop, tablet, and other mobile devices charged.

Fuel Capacity


You also need to find out how large the fuel tank in each generator is. This will ultimately determine how much continuous use you will be able to get from them.

A generator with a 4-gallon tank can give you up to 22 hours of use at a 25% load. The larger the tank, the longer you will be able to use it.

You should look for models that have an “eco mode” that is designed to conserve fuel. This can help you save quite a bit of money in the short and long term. It can also be very useful when you are in an emergency situation of some kind.

You’ll want to select one that can be start up fairly easily without too much hassle or frustration. Keep an eye out for models that have an electric start. This will help you save a lot of time and effort.

Control Panel


We recommend that you take a close look at the control panel on each generator that you come across. You should select one that has a fairly simple and straightforward design.

The control panel on your new generator should also have indicator lights for low oil and fuel. This will let you know when to refill, which is a pretty big convenience.

Many of these generators have a display that shows the remaining run time, voltage, frequency, and other things. This information can certainly be very useful.



If you are determined to find the best option, you’ll also need to consider each one’s size. There are plenty of compact models that are perfect for RV drivers.

Take a close look at the total dimensions and weight for these products. This will give you a better idea as to which ones will be easy to transport and move around. We recommend getting one that has a telescoping handle.

Safety Features


There are some safety features that you should look out for when shopping around. This includes auto shutoff, which can potentially prevent a fire. This will ensure that the generator automatically shuts down if the oil level is ever too low.



In order to find the greatest, you’ll want to take a close look at each one’s engine. It will need to offer at least 3200 watts. You should also take a close look at the various outlets that these generators have. A TT-30R outlet is required for use with a recreational vehicle.
