The Most Fuel Efficient RV – Overview 

How much the average MPG does an RV have?

most fuel efficient rv

Regarding fuel efficiency, RV mileage per gallon (MPG) varies depending on Class, length, and weight. If you’re after fuel economy, Class B RVs and camper vans are your best bet, boasting an MPG range of 18 to 25 miles. 

But if you need a larger living space, don’t despair – Class C motorhomes have an average fuel economy of 14 to 18 mpg. However, if you opt for a Class A coach, be prepared for lower fuel efficiency, which averages between 7 and 13 MPG. 

Remember that shorter and lighter RVs tend to be more fuel efficient, so choose your rig accordingly to make the most of your fuel economy.

Which factor does affect the RV’s fuel efficiency?


most fuel efficient rv

The terrain can significantly affect your RV’s fuel efficiency. Driving on hilly and mountainous roads greatly strains an engine, requiring more fuel to power the vehicle up and over these terrains. 

If you drive through these roads frequently, investing in a more fuel efficient RV is important to get the most out of each gas tank. 

Additionally, driving on flat terrain at higher speeds requires more power from the engine than at lower speeds, resulting in reduced fuel efficiency. Choosing routes with fewer hills and keeping your speed limit moderate can help increase your RV’s mileage per gallon.

Wind can affect the RV’s fuel efficiency in several ways. The most direct impact comes from an increased drag on the vehicle, which increases its resistance to forward motion and thus lowers fuel economy. 

This effect is particularly pronounced at higher speeds when wind speed begins to match or exceed that of the RV itself. 

Additionally, gusty winds can be dangerous for tall RVs and cause them to sway more than usual, which may lead to increased fuel consumption due to loss of control or out-of-control steering corrections from the driver. 

Finally, strong crosswinds can push the RV off course slightly or cause it to drift, again leading to a decrease in fuel economy from undesirable maneuvers and deviations from optimal route planning.

Driving habits

most fuel efficient rv

Driving habits have a big impact on the fuel efficiency of an RV. Drivers should practice defensive driving techniques such as avoiding hard acceleration, braking and cornering, maintaining a steady speed, and utilizing cruise control when available. 

The heavier the load on board, the less fuel efficient an RV becomes. Therefore, carrying necessary items and securing them properly to reduce the drag created while driving is important. 

Additionally, high wind resistance can significantly reduce fuel efficiency; by keeping windows closed and removing roof-mounted luggage racks or bike mounts that might increase air resistance when traveling at higher speeds, drivers can help improve their RV’s overall aerodynamics.

Fuel choice

most fuel efficient rv

The type of fuel used in an RV can affect its fuel efficiency. Gasoline-powered RVs are less efficient than diesel due to their weight and lower energy density. 

Additionally, they may require frequent fueling stops during road trips, increasing costs over the long run. Diesel-powered RVs offer more consistent performance and provide better fuel economy when traveling long distances, making them highly suitable for road trips and vacations. 

Furthermore, small diesel-powered RV engines also require less maintenance over time than gasoline engines. All these factors contribute to them being more cost-effective in the long run as compared with gasoline models.

A secondary vehicle

most fuel efficient rv

Towing a secondary vehicle behind an RV can significantly impact its overall fuel efficiency. The vehicle being towed adds to the total weight of the RV, increasing drag on the engine and making it work harder to move forward. 

Furthermore, air resistance increases when 2 vehicles are attached instead of just one, thus reducing the RV’s fuel efficiency. 

Therefore, if you plan to tow another vehicle behind your RV for long distances and over extended periods, consider renting or getting an alternative form of transportation for your secondary car to maximize your RV’s fuel efficiency. 

The cumulative amount of weight loaded into your RV

most fuel efficient rv

The cumulative weight loaded into an RV significantly impacts its fuel efficiency. Having additional items and cargo adds to the overall weight of the RV, reducing the miles per gallon (MPG) it can achieve. 

The heavier the load, the lower your MPG rating will be, which means you will use more fuel to maintain a certain speed. 

Moreover, having extra weight in your RV puts added stress on its components, such as brakes, tires, and suspension systems which can also lead to decreased fuel economy if they need to be fixed or need regular maintenance. 

Ultimately, keeping your RV’s load light and within its recommended capacity is one of the best ways to maximize its fuel efficiency over time.

The Most Fuel Efficient RV – Why Should I Choose It?

When choosing an RV, fuel economy is an important factor, but it may not be the only one. You may prioritize other features over gas mileage, depending on your needs and preferences. Here are common reasons you might choose an RV with lower fuel efficiency.

Larger Living and Sleeping Space

One of the main reasons RVers opt for larger, less fuel-efficient rigs is the need for more interior space. 

Class A and Class C RVs are typically larger than Class B vans, offering more room for living and sleeping. However, this additional space translates into more weight, which can lower fuel economy.

most fuel efficient rv

For families or groups of travelers, having ample interior space can make a big difference in comfort and convenience. If you plan to spend a lot of time inside your RV, having enough room to move around, relax, and sleep can enhance your overall experience. 

While you may spend more on gas, the benefits of a spacious RV may outweigh the costs.

Residential-Style Amenities

Another reason why RVers may choose a lower fuel economy is to enjoy the comforts of home on the road. While some of the most fuel-efficient RVs may lack certain amenities, such as a functional restroom or a fully equipped kitchen, larger RVs often come with a full range of residential appliances and features.

most fuel efficient rv

For example, you may prefer a shower, toilet, and sink in your RV rather than relying on campground facilities. Or, you may want a large refrigerator, oven, and stove to prepare and store your meals rather than relying on fast food or restaurants. 

By choosing an RV with a wider range of amenities, you can create a home-away-from-home that meets your needs and preferences.

Better Towing Capacity

If you plan to tow a second vehicle or trailer, you may need a more powerful RV to handle the extra weight. Diesel pusher RVs, typically larger and heavier, are well-suited for towing, offering more torque and horsepower. 

most fuel efficient rv

While towing can decrease fuel economy, having the ability to tow a boat, car, or another recreational vehicle can enhance your travel options and experiences.

Whether you choose a fuel-efficient or less fuel-efficient RV, it’s important to consider your specific needs and goals. You can find an RV that fits your lifestyle and budget by balancing fuel economy with other features, such as size, amenities, and towing capacity.

The Most Fuel Efficient RV – How To Choose?

Many travelers are turning to the RV lifestyle to explore new destinations. However, the fuel cost can be a concern for those who want to save money on their travels. Fortunately, there are ways to make your RV more fuel-efficient.


most fuel efficient rv

Vehicle class is one factor that greatly affects RV gas mileage. Large Class As and Class Cs are less efficient due to their size, weight, and shape, whereas smaller Class Bs have impressive gas mileage that rivals SUVs or pickup trucks.

Fuel Types

Another factor to consider is the type of fuel your RV uses. Gasoline is cheaper than diesel per gallon, but diesel engines are typically more fuel-efficient, saving you money in the long run. 

Additionally, many RV manufacturers are introducing electric-powered RVs, which could be the industry’s future.


most fuel efficient rv

Weight also plays a major role in your RV’s fuel efficiency. Heavier vehicles use more fuel, and manufacturers use materials that can make a difference in weight. 

Choose lighter models that use fewer materials in their construction. However, be mindful of slide-outs; they provide more living space but add weight to the RV.


The aerodynamics of your RV can greatly impact its gas mileage. Look for models with rounded front caps, which help reduce drag and improve fuel efficiency. Alternatively, some models have a more curved design that minimizes the boxy shape of traditional RVs.

By keeping these rules in mind, you can save money on fuel while enjoying the freedom and adventure of the RV lifestyle. With the advances in the industry, the future of RVing looks bright, as new models with improved fuel efficiency are being introduced every year.

The Most Fuel Efficient RV – Tips For Getting Better Fuel Efficiency In Your RV

If you’re looking for a fuel-efficient RV, several options are available. However, some factors might affect the gas mileage of your rig, such as the size, weight, and engine type. But don’t fret; there are ways to optimize your RV’s fuel consumption. 

These small tips can significantly affect your gas expenses, allowing you to travel longer without breaking the bank. So, whether you choose a small, compact RV or a larger model, you can still enjoy your road trips while getting the best gas mileage possible.

Keep Tire Pressure Optimal

most fuel efficient rv

One of the most important things you can do is to maintain the recommended tire pressure. The recommended tire pressure can be found on a sticker inside your RV, either next to the entry door or in the cockpit. Using the recommended tire pressure can significantly impact your fuel economy.

It is important to note that the recommended tire pressure displayed on the RV’s sticker differs from the tire pressure indicated on the sidewalls of the tires. 

This is because tire manufacturers create tires designed to work with various vehicles, but your RV manufacturer knows what is best for your specific RV model.

While it may be tempting to inflate your tires to a higher pressure to increase your fuel economy, we recommend following the tire pressure specified in your RV owner’s manual or on the sticker. 

This ensures that all your tires are filled to equal pressure, which is important for safety and handling.

most fuel efficient rv

Overall, maintaining the recommended tire pressure is one of the most effective ways to increase the fuel efficiency of your RV. By following the guidelines from your RV manufacturer, you can enjoy a more efficient and cost-effective journey on the road.

Become A Minimalist When Packing

One way to improve your fuel efficiency is to consider what you bring with you on your trip carefully. While packing everything and the kitchen sink is tempting, every additional pound of weight will negatively impact your gas mileage. 

If you plan on staying in one place for an extended time, rent gear like kayaks or bicycles instead of bringing them along.

Of course, fuel efficiency isn’t the only factor to consider when choosing an RV. Many types of RVs are available, each with pros and cons. 

For example, a class B RV is typically the most fuel-efficient option, but it can be cramped and uncomfortable for larger groups. A Class A RV, on the other hand, offers plenty of space and amenities but can be extremely expensive and difficult to maneuver.

most fuel efficient rv

Ultimately, choosing the most fuel-efficient RV for your needs will require careful consideration of your budget, travel plans, and personal preferences. However, by taking the time to research and make informed decisions, you can help ensure that your next RV trip is both comfortable and cost-effective.

Check And Change The Engine Air Filter 

Maintaining the health of your RV’s engine air filter is vital to ensure it is the most fuel-efficient. As a rule of thumb, checking the status of your filter whenever you change your oil and oil filter is a sound practice. 

If you observe that your filter is obstructed or light cannot pass through it, it is necessary to replace it immediately.

Your RV’s engine relies on a steady supply of clean air from the air filter to perform at its best. A blocked filter reduces airflow and consequently decreases the engine’s performance. 

Neglecting air filter maintenance can lower your RV’s fuel efficiency, causing it to consume more fuel and cost you money in the long run. The financial implications of ignoring the problem exceed the cost of a new air filter.

If you are still determining what a dirty air filter looks like, a mechanic will happily show you during your next routine RV service. Keeping your air filter in top condition guarantees higher fuel efficiency and a smoother-running RV.

Maintain The Engine And Transmission

One crucial factor that affects fuel consumption is the engine and transmission condition. Regular maintenance, such as fluid checks and replacements, tire rotations, and differential services, can significantly improve your RV’s fuel economy.

To determine which maintenance tasks are needed, refer to your RV’s owner’s manual, which provides a comprehensive guide on maintenance schedules based on the odometer reading.

It’s also worth noting that how you drive your RV can also affect its fuel efficiency. Ensure you avoid aggressive driving, maintain a steady speed, and avoid excessive idling to maximize your RV’s fuel economy.

Overall, keeping up with maintenance and conscientious driving can help you save on fuel costs without compromising your travel adventure.


Consider a few things when choosing the most fuel-efficient RV for your next adventure. The size and type of vehicle will play an important role in determining how much gas mileage you can get out of each tank. 

Additionally, aerodynamic design, weight reduction technology, and advanced engines can contribute to improved fuel economy. With careful research into these factors, you’ll be well on your way to finding the perfect RV that offers both performance and efficiency for your travels ahead!
