How Much Does It Cost To Fill An RV Gas Tank?
It can cost anywhere from $100 to $600 to fill up an RV gas tank in the United States. The cost will also depend on the type of RV, as different classes of RVs have different fuel efficiency and tank sizes.
Class A RV Fillup Cost
Class A RVs are the largest and most luxurious type of RV. They typically have the largest gas tanks, averaging around 100 gallons, and the average cost of a gallon of gas in the US in 2023 is $3.55.
100 gallons of gas x $3.55 per gallon = $355.00.
So the average cost to fill a Class A RV gas tank would be $355.00.
It can cost up to $710 to fill up a King Aire, which has a 200-gallon tank. A Dutch Star, which has a 150-gallon tank, can cost around $535 to fill up.
Class B RV Fillup Cost
Class B RVs are smaller and more affordable than Class A RVs. Class B RVs, also known as camper vans, have smaller gas tanks similar to traditional vehicles, typically around 25 gallons.
25 gallons of gas x $3.55 per gallon = $88.75.
So the average cost to fill a Class B RV gas tank would be $88.75.
Class C RV Fillup Cost
Class C RVs are smaller and more affordable than Class A RVs and larger than Class B RVs, thanks to their motorhome built around a cutaway chassis. The average Class C gas tank size is around 50 gallons.
50 gallons of gas x $3.55 per gallon = $177.50.
So the average cost to fill a Class C RV gas tank would be $177.50.
The cost of filling up an RV gas tank also depends on the price of gas. Gas prices can vary greatly depending on location and time of year. As of July 2022, the average price of gas in the United States is around $3.15 per gallon. However, gas prices can range from $2.50 to $4.00 per gallon.
When planning a trip in an RV, it’s important to factor in the cost of fuel. Budgeting for gas expenses can help ensure that you have enough funds for your entire trip.
Knowing the size of your RV gas tank and the average cost of gas in your area can help you estimate the cost of filling up your tank.
Cost Factors for Filling Up an RV
When planning a road trip with an RV, one of the most significant expenses to consider is the cost of fuel. The amount of money it takes to fill up an RV depends on several factors, including the size of the RV’s gas tank, the type of fuel used, and the current gas prices. In this section, we will examine these factors and how they affect the cost of filling up an RV.
RV Gas Tank Sizes
The size of an RV’s gas tank plays a crucial role in determining the cost of filling it up. RVs come in different sizes, and their gas tanks vary accordingly. The larger the RV, the bigger the gas tank, and the more fuel it needs to fill up. Class A RVs, which are the largest, can have gas tanks that hold up to 150 gallons of fuel. Class B and Class C RVs, which are smaller, have gas tanks that hold between 20 and 50 gallons of fuel.
Type Of Fuel Used
The type of fuel used by an RV also affects the cost of filling it up. Most RVs use either gasoline or diesel fuel.
Diesel fuel is generally more expensive than gasoline, but diesel engines are more fuel-efficient. Therefore, an RV that uses diesel fuel may cost more to fill up but can travel further on a full tank than an RV that uses gasoline.

Gas Prices
The current gas prices in the area where you plan to fill up your RV also affect the cost of filling it up. Gas prices can vary significantly from one location to another, and they can fluctuate over time.
For example, gas is usually the cheapest in X, and the most expensive in X and X.
Therefore, it is essential to check the gas prices in the area where you plan to fill up your RV and factor them into your budget.
RV Trip Fuel Cost Calculator
Planning an RV trip can be a lot of fun, but it’s important to budget for fuel costs. One way to do this is by using an RV trip fuel cost calculator. This tool helps you estimate how much you’ll spend on gas for a specific trip, so you can plan accordingly.
Know Your RV’s Gas Mileage
Before you use an RV trip fuel cost calculator, it’s important to know your RV’s gas mileage. This can vary depending on the size and type of your RV, as well as other factors like the terrain you’ll be driving on and your driving habits.
To calculate your RV’s gas mileage, fill up your tank and record the odometer reading. You can lookup your RV’s fuel tank capacity in your owner’s manual or on the manufacturer’s website.
Then, drive your RV until the tank is almost empty and fill it up again. Record the number of gallons you used and the new odometer reading.
Divide the number of miles you drove by the number of gallons you used to get your RV’s gas mileage:
Miles / Gallons = Miles Per Gallon (aka RV Gas Mileage) Reading.
Once you know your RV’s gas mileage, you can take the total number of miles you’ll be driving on your trip and calculate how many gallons of gas you’ll use:
Total Trip Miles / RV Gas Mileage = Total Gallons of Gas Needed.
Lastly, take the total gallons of fuel you’ll need and multiply it by the current cost of fuel to see what your fuel costs will be:
Total Gallons of Gas Needed x Current Fuel Price = Total Cost Of RV Fuel for Trip.
