How Many Miles Per Gallon Does an RV Get?

Before one decides to embrace the RV life, one of the most important questions that should be addressed is fuel efficiency. Any cost is important, and in this case, fuel consumption can seriously affect your budget if not thought out thoroughly.

You see, RV works differently than regular automobiles so it’s not safe to assume fuel efficiency just like that.

So Just How Many Miles Per Gallon Does an RV Get?

Class A is at 7-10mpg
Class B is at 10-25mpg
Class C is at 8-12mpg

When we were deciding as a family what we should get, research helps a lot. We had a few things to consider and fuel cost is one of them.

Just because a family can afford an RV doesn’t necessarily mean they should splurge on fuel.

That is the case for us. We had to look around for what is most efficient for us in terms of fuel consumption.

Before we reached a decision, we asked the question how many miles per gallon (mpg) does an RV get.

Here’s what we gathered during that time.

We were trying to decide which class we should get and made the comparison as such, find more about the different types of RVs here.

Class A is at 7-10mpg
Class B is at 10-25mpg
Class C is at 8-12mpg

Generally speaking, the larger the RV, the lower the miles per gallon. It also matters if you are towing additional cars or trailers as it would add more weight to the RV while running.

Let me share with you how it works based on the three primary classes of RV.

Class A Fuel Efficiency

Class A RVs are the largest among the three classes, usually 29’ to 45’ in length. It’s also the most luxurious, having enough space for bedrooms, bathrooms, living room, and kitchen among others.

But how efficient are they when it comes to fuel consumption?

As mentioned, the average of Class A RVs is 7-10mpg. Because it’s the largest and the heaviest, it has the least mileage compared to Class B and Class C.

Class B Fuel Efficiency

Among the three classes, Class B is the smallest whose length is around 18’ to 24’. It’s the smallest and shortest among the three, and therefore has the longest mileage, with an average of 10-25mpg.

Class C Fuel Efficiency

Considered as the middle ground between Class A and B, Class C has more features than Class B.

RVs of this class are around 30’ to 33’ long, with average mileage of 8-10mpg.

Given this comparison, it relatively shows that the gas mileage is greatly affected by the size of the RV.

How Many Miles Per Gallon Does a v10 RV Get?

The v10 engine is strong and has great performance.

Its average, just like the average for majority of the RVs is around 7-10mpg. Although, this average will also depend on some factors.

For instance, RVs going downhill will potentially have higher mpg’s, thus higher mileage.

On the other hand, RVs going uphill possibly have lower mileage due to more fuel consumed or higher RPM.

I’ve looked around for some info and I can’t seem to find a standard here, but according to fellow RVers, the figures play around 7-10mpg.

You may observe your mileage during each trip and get your actual average after several trips. But most likely, you’ll get approximately the same or somewhere near this average.

How Many Miles Per Gallon Does a Diesel Motorhome Get?

Diesel motorhomes are normally up to 45’ long. The engine is near the back most of the time, being the reason they are called diesel pushers.

Compared to other RVs, they are known to deliver more torque and work better at towing larger trailer vehicles.

Since these motorhomes are generally larger than other RV types, it’s heavier in weight as it can accommodate more space and features such as bigger sleeping facilities and the like.

As such, we can’t expect its fuel efficiency to be the same as that of smaller RV models.

Remember, the general rule is that the bigger the RV, the lesser the mpg is. Same rule applies regardless if your RV is gas or diesel-powered.

Based on the common feedback of other RV enthusiasts, the general average of diesel motorhomes ranges from 9-14mpg.

If your motorhome is brand new, you will get better fuel efficiency. If your motorhome is secondhand, then don’t expect as much efficiency as the new one.

I hope you set the right expectations there.

For us, RVing isn't about having the biggest RV and the best gear. It's the feeling you get when you wake up early in the morning and take your first big breath of mountain air. It's about teaching our kids about our natural world and watching them explore nature. If you allow yourself to slow down and disconnect from the modern world and reconnect with nature, you will feel energized, happy, engaged and inspired. That's how we feel anyway :) We have 3 kids and a dog and this blog is about our past RV adventures, future plans and all the supplies and gear you need to stay safe and have fun.
