RV fuel costs add up quickly

How much will it cost to fill up your RV? According to the team at, It depends on the size of your vehicle and how far you’re traveling. They explain that RV trips, on average, are around 5,000 miles.

Many recreational vehicle manufacturers claim their vehicles get somewhere between 10 and 20 mpg. So using an average cost of $2.50 to $4.00 per gallon of gas, says that a full tank of gas for your RV can be anywhere from $60 to $600.
But there are different sizes so let’s take a closer look. Class A vehicles are smaller, get 8 to 10 mpg, and have tanks that hold 100 to 150 gallons of gas. Class B vehicles including camper vans usually get 10 to 25 mpg. Class Bs can usually hold 25 gallons of gas. Class C vehicles, motorhomes, get 10 mpg and hold 25 to 55 gallons.

Other factors to consider

The cost to fill up your recreational vehicle will depend on whether it takes gas or diesel. Those who routinely drive long distances usually favor diesel because they get better gas mileage. Diesel is a more efficient fuel source but it’s often more expensive. Diesel isn’t always available at all gas stations so it’s a good idea to check the stops on your route so you’ll know where you can gas up.

Your gross vehicle weight also has an impact on how much gas your RV will cost. GVW is the total weight your RV can meet and still be road safe. The more the RV weighs the more gas you burn. An RV with a higher GVW rating will not be as fuel-efficient.

According to the folks at, just because you can doesn’t mean you should. Just because your RV can be up to a certain weight doesn’t mean you need to push it to the limits. By optimizing the overall weight of your rig, you can save money on fuel costs. If there’s a place where you can grocery shop when you reach your destination, for example, the RV would weigh less than if you had a full pantry of food.
