              • Pricey

              First off, is the Champion 3400-watt with emphasis on duel fuel. This feature allows you to use either gasoline or propane to operate your machine.

              For those who don’t know, propane is one of the cheapest and cleanest burning kind of fuel. I mean, if not using your generator regularly, you don’t need to remove the oil like when with gasoline.

              The whole construction of this unit is also user-friendly, especially the multiple outlets that you can charge different electronic appliances at once.

              At the meantime, a quick Touch Panel will let you access all the controls in one convenient area while the push-button electric start ensures a quick start in the winter.

              While running at 3100 watts – also the most powerful out of three inverter options in this list, its noise level is incredibly low, only 59 dBA.

              • Heavy and difficult to lift it up just by one person

              • Oil drain is poorly located

              Like the previous sibling, Champion 3800-watt highlights the duel fuel function that delivers variable fuel type choices. Either you can go for gasoline as a budget-friendly option or propane for clean burning.

              It also keeps other strengths of general Champion generators like the Safety fuel selector switch, Touch start, Automatic Low Oil Shutdown, and Fuel Gauge.

              But since this is a conventional model with leverage in the fuel tank (3.4 gallons), the runtime now is improved up to 9 hours on a full load.

              At the meantime, with a 212cc OHV 4 Stroke Rainier engine, the power capacity is increased to 3800 running watts and 4750 starting watts, which ensures more electricity for more appliances.

              Compared to other counterparts, this unit is unbeatable. But such that phenomenal performance leads to two minus weaknesses: heavier weight (105 lbs.) and louder noise (68 dBA).

              How To Choose The Best Generators For Travel Trailer?

              Type of generator & fuel

              In other words, you should consider which one to choose: An inverter or a conventional generator?

              Inverter generators

              Conventional generators

              How does it work?

              Made by recent state-of-the-art magnets & advanced electronic circuitry

              Generate electricity by powering a motor that’s attached to an alternator

              Highlight feature

              Can convert the current to DC voltage and then invert it back to AC voltage.

              Runs at a constant speed to provide the needed electrical current


              -Produce safer power (less than 3% total harmonic distortion)

              -Smaller sizes

              -Lighter and easier portability

              -More efficient


              -Can provide a huge amount of power (up to 50,000 watts)



              -Need to refill fuel more times than the conventional generators


              -Bulkier and heavier

              -Only for large electronic appliances


              Best for

              Sensitive appliances

              Those people who require a huge amount of power for their devices

              On tight budget

              The fuel source is another must-consider. There are:

              • Diesel: It’s the most powerful kind of fuel that not only produces clean burning but also is safer than gasoline. But diesel is the costliest on the other hand.

              • Gasoline: It’s relatively affordable and powerful out of three. If you choose this kind of power source, take note to remove gasoline off your generator if not regularly used because it’s not clean burning.

              • Propane: The cheapest fuel source in this list while providing the cleanest burning to be the best eco-friendly option. However, it’s the least powerful and portable.

              Power output

              • Since most modern travel trailers contain lots of luxuries that usually present at home, your generator should be capable of running all of them without draining fully its fuel supply.

              • Estimating accurately the specific amount of power for your recreational vehicle turns out to be a must before purchasing a generator. Neither too little nor too much will have its consequence.

              • I advise making a list of the electronics, including their starting wattages and running wattages. Then, add the highest start-up requirement with the start-up wattage of the electronics to calculate the surge capacity you need in a generator.

              • If you intend to use it permanently, look for a model that features parallel capabilities to let you switch to another generator when the power needs are up.

              Noise level

              • A noisy generator might spoil you and your neighbors' outdoor experience, which is the reason I suggest choosing a quiet one.

              • But take note that the more silent the generator, the less powerful it is.

              • Inverter generators are the most favorite choice for people who want to get a silent night sleep since thanks to the advanced technologies to get a perfect compromise of power and noise level.

              • Usually, their noise range is only within 50-60 dBA at a 23-feet distance, which is best for campsites.

              • But if your travel trailer requires a huge amount of power, I’ve got two options for this case: Choose a conventional generator that’s equipped with mufflers or an inverter with parallel capability.


              • Unlike a generator for home use, the one for travel trailers requires more on maneuverability since you have to move it here and there during your trips.

              • Choosing a lightweight and compact model is highly recommended, but if yours is heavy, at least it should have some handles that you can lift it up easily and share the heft with others while carrying it around.

              • Or, finding ones with wheel attachment is convenient for one person to move their generator on their own.

              Which Brands Make The Best Generators For Travel Trailer?


              Started making power equipment since 2003, that’s the reason Champion is now really a champion in the generator world. Their lines are vast in designs, sizes, power output, and budgets while the customer service is really top-rated.


              Wen’s generators aren’t the most powerful models on the market, but the produced energy from their products are always guaranteed to be clean and safe. The real strength lies in incredible silence level when running, making Wen’s generators are ideal for good night sleeps.


              Westinghouse is a well-known brand specialized in generators and pressure washers with an emphasis on long-standing engineering history since 1865. Up to now, there are 20 different lines of generators and their general highlights are a powerful engine and especially, fuel efficiency.


              DuroStar has joined the list of highest-quality generators so far but what really gains their reputation is the price – very affordable. That’s why any beginners who are looking for an entry-level model for their trailer, this is always the first choice.


              Rainier might sound unfamiliar to some people since it’s a newcomer in this industry however, the amazing silence of their products is soon well-loved by worldwide users. While featuring powerful engine and durable construction, its price is kept low to fit many people’s budget.


              Do you need a generator for a travel trailer?

              Yes, you do. Since battery can’t always be relied upon as a reliable power source, it’s essential to have a generator in your travel trailer.

              How much gas does travel trailer generator use?

              It depends on two things:

              • Your usage

              • Fuel type

              A 5000-watt gasoline-operated generator consumes 1 gallon of fuel per hour while one that’s run by propane will be around 1 to 1.5 gallons. Diesel is the most fuel effective since it just takes 0.75 gallons.

              How many watts does a travel trailer use?

              To answer this question, look at the load you intend to power via the travel trailer at the same time. Note the name, their starting watts, and running watts. Then, add all the starting watts group to know how much surge watts your trailer needs.

              Is inverter better than a traditional generator?

              An inverter generator is just better than a traditional model in some aspects, such as compactness, lightness, silence, and safety to sensitive electronics.

              In terms of price range and power capacity, the traditional generators win.

              Can my generator get wet?

              No, it can’t. Since water and electricity are their enemies, it’d better not run your generator in a wet or rainy environment. To avoid bad cases happened, you should use a GFCI outlet that will auto-shut off when your machine is wet.

              Can you run a generator overnight?

              Literally, you can. But I advise you not to ensure safety and your neighbors will also thank you for that choice as well.

              Is it bad to run a generator without load?

              Yes, it is. The most serious consequence of running a generator without load is wet stacking. When the fuel isn’t burnt off entirely, the excess amount will accumulate on the exhaust stack and turbo, leading to irreversible damage. It hurts your bank!


              In your search for the best generator for a travel trailer, ensure to go for a model that comes with the most optimal compromise of your budget, enough power capacity, and size. I hope that this ultimate buying guide was helpful to you. Thanks for reading!
