Introduction

Hitting the open road in an RV is one of the best ways to explore the country. You have the freedom to go wherever you want, sleep in your own space, and enjoy the great outdoors. But as fun and exciting as RV travel is, there’s one thing that can quickly eat into your budget: fuel costs.

RV fuel expenses are a significant part of any road trip budget, and they can vary widely depending on your RV type, driving habits, and the route you choose. In this blog, we’ll break down how to estimate fuel costs, the differences between gas and diesel RVs, and share practical tips to save money on fuel so you can focus more on the adventure and less on the expense.

Estimating Fuel Costs for Your RV Trip

Know Your RV’s Mileage

RVs come in all shapes and sizes, and their fuel efficiency varies just as much. Here’s a quick guide to the average miles per gallon (MPG) you can expect based on RV type:

• Class A Motorhomes: These are the largest RVs, often luxurious and spacious, but their size means they’re fuel-hungry. Expect an average of 6-10 MPG.
• Class B Motorhomes (Camper Vans): These compact and efficient RVs get better mileage, typically 18-25 MPG.
• Class C Motorhomes: Falling between Class A and B in size, Class C RVs usually get around 10-15 MPG.
• Travel Trailers and Fifth Wheels: These are towed by a vehicle, so your mileage depends on your tow vehicle. Trucks towing these trailers average 8-15 MPG.

Calculate Your Route’s Fuel Costs

Once you know your RV’s MPG, calculate your fuel costs using these steps:

1. Estimate the Distance: Use a map or GPS app to determine the total miles for your trip.
2. Determine Fuel Needs: Divide the total miles by your RV’s MPG to get the number of gallons you’ll need.
3. Check Fuel Prices: Find the average cost of fuel along your route (use apps like GasBuddy).
4. Calculate Costs: Multiply the gallons needed by the fuel price to get your total fuel expense.

For example, if you’re driving a Class C RV with 12 MPG on a 1,200-mile trip and the average fuel price is $4 per gallon:

• Total gallons needed = 1,200 ÷ 12 = 100 gallons
• Total fuel cost = 100 x $4 = $400

Gas vs. Diesel RVs: Which is Better for Your Wallet?

When choosing an RV, you’ll often face the decision between gas and diesel engines. Each has its own advantages and drawbacks, especially when it comes to fuel costs.

Gas RVs

Pros:

• Lower upfront cost: Gas RVs are typically cheaper to purchase.
• Widespread availability: Gas stations are everywhere, so finding fuel is easy.

Cons:

• Lower fuel efficiency: Gas engines generally get fewer miles per gallon than diesel engines.
• Shorter engine lifespan: Gas engines may require more frequent maintenance over time.

Average Mileage: Gas-powered RVs usually get 6-12 MPG, depending on size and type.

Diesel RVs

Pros:

• Better fuel efficiency: Diesel engines get more miles per gallon, saving you money on long trips.
• Longer engine lifespan: Diesel engines are known for durability and longevity.
• More power: Diesel engines handle heavy loads better, making them ideal for large Class A motorhomes or towing trailers.

Cons:

• Higher upfront cost: Diesel RVs and diesel fuel are generally more expensive.
• Limited availability: Diesel isn’t as readily available in some rural areas.

Average Mileage: Diesel-powered RVs average 8-15 MPG, which is slightly better than gas counterparts.

Tips to Save Money on RV Fuel

Fuel costs don’t have to break the bank. Here are practical tips to stretch your dollars:

1. Drive Smart

• Maintain a steady speed: Avoid sudden accelerations and frequent braking.
• Use cruise control: On highways, cruise control can improve fuel efficiency.
• Stick to 55-65 MPH: Driving slower reduces wind resistance and saves fuel.

2. Lighten the Load

• Pack only essentials: Extra weight increases fuel consumption.
• Empty tanks when possible: Travel with minimal water in your fresh, gray, and black tanks.

3. Plan Efficient Routes

• Avoid hilly terrain: Uphill driving burns more fuel.
• Minimize detours: Plan your route to reduce unnecessary miles.
• Check traffic: Avoiding congested areas saves both time and gas.

4. Monitor Tire Pressure

• Properly inflated tires reduce rolling resistance and improve MPG. Check your tire pressure regularly, especially before long trips.

5. Use Fuel Apps

• Download apps like GasBuddy or Waze to find the cheapest fuel prices along your route.

6. Consider Membership Discounts

• RV clubs like Good Sam or AAA often offer fuel discounts at partnered gas stations.

7. Travel During Off-Peak Times

• Fuel prices can fluctuate based on demand. Traveling mid-week or during off-peak seasons can help you save.

Conclusion

Fuel costs are a significant factor in RV travel, but with careful planning and smart driving habits, they don’t have to drain your budget. Understanding your RV’s fuel efficiency, choosing the right engine type, and following money-saving tips can make your road trip more affordable and enjoyable.

Whether you’re traveling in a compact camper van or a luxurious Class A motorhome, being mindful of fuel expenses allows you to focus on what really matters: the journey and the memories you’ll make along the way. So, fill up your tank, hit the road, and enjoy the adventure without worrying about breaking the bank.
