How much MPG does an RV get?

RVs, or recreational vehicles, have become an increasingly popular way for people to travel and vacation. Offering the comforts of home while on the road, RVs provide a convenient and flexible way to explore the countryside. However, with the freedom of the open road comes the responsibility of gas mileage and fuel efficiency. For RV owners, understanding how much MPG their RV gets is an important part of trip planning and budgeting. This article will provide a comprehensive overview of RV gas mileage, including average MPG estimates, factors that affect RV fuel economy, and tips for improving mileage. Whether you’re a new or experienced RV owner, learning more about RV MPG will ensure your travels are efficient, cost-effective, and worry-free.

What is the average gas mileage for an RV?

Many factors determine RV gas mileage, making it difficult to pinpoint an exact average. However, most sources estimate RV MPG between 6 to 12 miles per gallon. The type and size of the RV, engine performance, and driving habits all impact efficiency. Here’s a breakdown of the average MPG estimates for different RV classes:

Class A Motorhome

The largest RV category, Class A motorhomes can reach up to 45 feet in length. Driven like a bus, they typically achieve 6 to 10 MPG. Larger models and older vehicles sit at the lower end of this range.

Class B Camper Van

The smallest RV class, Class B camper vans are van conversions designed for 2 to 4 people. Their smaller size and aerodynamic shape allow for 10 to 15 MPG. Custom van builds with efficient engines can reach up to 20 MPG.

Class C Motorhome

Class C motorhomes fall in between Classes A and B for size. Also known as mini-motorhomes, they usually get 8 to 12 MPG. Better mileage depends on length, roof height, and other factors.

Travel Trailer

Since travel trailers are towed rather than driven, their mileage depends on the towing vehicle. Expect a towing MPG of 8 to 12 MPG. Lightweight trailers towed by smaller trucks may reach up to 15 MPG.

Fifth Wheel Trailer

Similar to travel trailers, fifth wheel MPG relies on the tow vehicle. They’re typically towed by heavy-duty pickups, which often achieve 10 to 12 MPG while towing. Larger fifth wheels further reduce efficiency.

Pop-Up Camper

Pop-up campers are lightweight towables that get the best RV MPG – averaging 14 to 18 MPG when properly paired to a smaller tow vehicle. Their aerodynamic shape and canvas sides improve efficiency.

What affects RV gas mileage?

While the RV class and size provide a general MPG estimate, many other factors influence fuel efficiency:

Vehicle Weight

Heavier RVs require more power to accelerate and maneuver, which directly affects MPG. Newer RVs often feature heavier amenities, reducing efficiency. Travel light and remove unneeded gear to improve mileage.

Aerodynamics

An RV’s shape impacts how smoothly air flows around the vehicle. Bluff front profiles characteristic of Class A motorhomes reduce efficiency. Compare a pop-up’s sloped shape to a Class A’s flat walls and roof.

Engine Size

Larger engines consume more fuel. Choose the smallest engine capable of comfortably moving the RV, especially for tow vehicles. Perform regular maintenance to keep the engine in optimal shape.

Towing Capacity

Make sure your tow vehicle is suited for the RV’s weight and has enough power. Exceeding capacity strains the engine, lowering MPG. Match your truck to the trailer’s limits.

Tire Condition

Underinflated or damaged tires increase resistance and drag, wasting fuel. Check tire pressure before each trip to maximize MPG. Keep tires properly balanced with good tread depth.

Speed and Acceleration

The faster you drive, the more fuel consumed. Rapid acceleration and high speeds burn gas quicker. Maintain steady pacing and coast rather than constantly braking. Speed limits around 55-65 MPH optimize MPG.

Terrain and Elevation

Hilly, mountainous routes reduce MPG since steep grades require more throttle. Heavily loaded RVs struggle even more with elevation. When possible, plan flatter travel routes to save on gas.

Headwinds

Driving against strong headwinds requires extra effort from the engine, lowering MPG. To improve efficiency, limit high-speed highway driving on extremely windy days.

Tailwinds

On the other hand, tailwinds work in your favor by essentially giving you a push. MPG will increase when driving with a strong tailwind. Capitalize by covering more miles in these conditions.

Road Conditions

Bumpy, poorly maintained roads with potholes and cracks decrease MPG. Soft dirt or gravel roads also reduce efficiency. Try to stick to smooth asphalt or concrete highways whenever possible.

Accessories and Use

Items like roof racks, air dams, and bug deflectors help streamline airflow for better MPG. Using accessories like the generator, roof A/C, and appliances draws power from the engine.

Driving Habits

Aggressive driving behaviors including rapid acceleration, hard braking, and high speeds waste huge amounts of gas. Keep speeds moderate with gentle acceleration and braking for optimal efficiency.

Tips for Improving RV MPG

While RV MPG largely depends on fixed factors like size and weight, certain adjustments can help boost your efficiency:

Lighten Your Load

Avoid overloading your RV with unnecessary gear. Extra weight strains the engine, decreasing MPG. Pack light and remove heavy equipment when not needed.

Maintain Steady Speeds

Accelerating, braking, and varying speed waste gas. Maintain a steady pace without aggressive maneuvers. Use cruise control to help stick to constant speeds.

Lower Highway Speeds

Following lower speed limits optimizes efficiency. Each 5 MPH over 50 MPH reduces MPG significantly. Stay around 55-65 MPH on highways for big MPG gains.

Coast More, Brake Less

Coasting allows momentum to carry you farther without burning extra fuel. Avoid continuous braking. Time lights to coast as often as possible.

Plan Efficient Routes

Choose routes with lighter traffic, gentle grades, and smooth roads when possible. Avoid hilly terrain and dirt roads that reduce efficiency.

Check Tire Pressure

Incorrect tire pressure drags down MPG. Inflate to the recommended PSI before each trip. Check both RV and tow vehicle tires.

Use Cruise Control

Cruise control maintains a steady speed without constant throttle adjustments that waste gas. Use it whenever appropriate to improve MPG.

Limit Generator Use

RV generators siphon power from the engine, lowering MPG. Only run when necessary. Use campsites with hookups to avoid relying on the generator.

Close Windows and Vents

Open windows and vents increase aerodynamic drag. Driving at higher speeds, close all openings to prevent wasted energy fighting air resistance.

Change Air Filters

Replace clogged air and fuel filters that strain engine performance. Fresh filters allow optimal airflow and MPG.

Perform Regular Maintenance

Follow the manufacturer’s maintenance schedule for tune-ups, oil changes, filter replacement and spark plug service. Proper maintenance maximizes mileage.

Maximizing efficiency on your RV road trip

While real-world MPG depends on variable conditions, you can plan ahead to maximize efficiency on an RV trip:

Match the Tow Vehicle to Trailer

Make sure your towing vehicle has an appropriate tow rating for the RV’s fully loaded weight. Undersized vehicles struggle and waste fuel.

Use Fuel Efficient Driving Habits

Gentle acceleration, coasting, slower speeds, and cruise control optimize MPG. Avoid aggressive maneuvers that burn extra gas.

Pack Light and Remove Weight

Every pound counts when it comes to road efficiency. Bring only essentials and store gear you won’t need.

Plan Routes Strategically

Use apps to choose flat, direct routes on well-maintained roads. Avoid excessively hilly or winding roads.

Follow Recommended Tire Pressures

Check tire pressure before departure. Low pressure strains the engine. Keep properly inflated for minimum resistance.

Service Your RV Pre-Trip

Inspect belts and hoses. Replace air, fuel, and oil filters. A finely tuned engine optimizes MPG.

Modify Speed Based on Conditions

Slow down for headwinds which require more effort. Take advantage of tailwinds with slightly higher speeds.

Use Apps to Track Mileage

GPS apps help monitor MPG performance. Note mile markers and gas station fill ups. Identify areas to improve.

Conclusion

While RVs are not known for impressive MPG compared to smaller vehicles, owners can still maximize their efficiency. Typical gas mileage ranges between 6 MPG for large Class A motorhomes up to 18 MPG for streamlined pop-up campers. Many factors like weight, aerodynamics, terrain, and driving habits affect MPG. Planning efficient travel routes, proper maintenance, and adjusting driving behaviors can help boost your RV’s mileage. Focus on steady speeds, gentle acceleration, reduced loads, and smooth roads. With some preparation and awareness, RV travelers can extend their mileage and get the most out of every gallon.
