What Is A Diesel Pusher?

If you are shopping for a drivable RV like a motorhome or motorcoach, you have probably heard the term “diesel pusher.” For new RV buyers, this term can make some RVs seem daunting. However, a diesel pusher is actually a great option when it comes to efficient, powerful RVs.

In this article, we will explore the diesel pusher and help you navigate the difference between diesel engines and gas engines. If you are already shopping for a diesel pusher RV, we will even offer a few options for you to consider.

What Is A Diesel Pusher?

Though it sounds technical, a diesel pusher is just a motorhome with the engine in the rear instead of the front. This kind of motorhome first hit the market in the 1940s. Prior to this time, all motorhomes had the engine in the front.

All diesel pusher RVs use diesel fuel instead of regular gasoline. This comes with some advantages and some disadvantages. However, many people find that diesel pushers tend to have a bit more power which can be advantageous depending on where you like to vacation.

10 Reasons Diesel RVs Are Better Than Gas?

Before you run out and buy a diesel pusher motorhome, it is helpful to understand the pros and cons fully. Here are ten reasons that a diesel pusher is better than a gasoline engine.

1. Is Gas Or Diesel Better For A Motorhome?

If you are not familiar with diesel engines, the first thing you will learn about diesel pushers is that they can run for a long time. Because diesel burns differently in the engine than gasoline, it tends to create less wear on engine parts. 

This slow burn of fuel also allows diesel engines to run more efficiently and generates more power. If you are looking for a more robust and powerful RV, a diesel pusher is a great option.

On the comfort side of things, diesel pushers tend to have more luxurious amenities. You can get a really comfortable gasoline RV, but diesel pushers are the way to go if you want to step up the comfort.

2. How Many Miles Per Gallon Does A Diesel Pusher Get?

How Many Miles Per Gallon Does A Diesel Pusher Get

One of the benefits of owning a diesel pusher over a gasoline RV is that they tend to get better fuel mileage. Most diesel pushers average 8 to 14 miles per gallon. Class A gasoline RVs will have a lower fuel efficiency on average. 

Most gasoline motorhomes get between 6 and 10 miles per gallon. If you plan on driving in remote areas, a diesel pusher gives you a longer driving range.

3. Do Diesel Pusher Motorhomes Have Less Maintenance?

Diesel pushers do not require as much maintenance as gasoline RVs. A diesel pusher is a great way to find savings if you want to minimize maintenance costs. It is important to point out that if your diesel pusher needs repairs, engine parts are more expensive than gas RV engines.

The best way to avoid these repair costs is to keep up with your diesel pusher motorhome’s maintenance and consider purchasing an extended warranty to protect you from the high costs of repairs.

4. Do You Plan On Being A Full-Time RVer?

If you are looking to be a full-time RVer, a diesel pusher may be worth considering. Diesel pushers tend to have more interior space and frequently have more storage than gasoline Class A motorhomes. Not only will you have more places for your stuff, but there is more living space for you.

5. Diesel Pusher Motorhomes Can Pull More Weight

Diesel Pusher Motorhomes Can Pull More Weight

Diesel engines are more powerful, which means they can pull more weight. A diesel pusher Class A motorhome has an average towing capacity of 10,000 to 20,000 pounds. On the flip side, a gasoline Class A motorhome can only tow between 5,000 and 10,000 pounds. A diesel pusher is a must if you want to tow a larger vehicle or even a boat.

6. The Top-Rated Motorhomes With Luxury Features Are Diesel Pushers

If you want to buy a motorhome with great reviews and luxurious features, you will quickly find that your best options are diesel pushers. Yes, there are some great gasoline options out there that are highly rated and loved by their owners. However, when it comes to luxury rigs, the top-rated options are all diesel pushers.

7. Diesel Pusher Motorhomes Offer A Smooth And Quieter Ride

When it comes to a comfortable ride, you are going to love what a diesel pusher offers. First, with the engine in the back of the rig, you do not have to listen to the engine under your feet as you drive. This quiet driving experience allows you to have conversations or enjoy music without the added sound of the engine. 

Most manufacturers of diesel pushers tend to add other features for travel comfort. These additional features may include active steering systems, air ride suspension, and independent axles. These features will improve the smoothness of the ride and make driving a diesel pusher easier.

8. Diesel Pushers Depreciate Better Than Gas Motorhomes

Have you ever heard that the minute you drive a vehicle off the dealership lot, it loses 30% of its value? Motorhomes and RVs also lose 20% of their value when you drive off the sales lot. However, if you are considering a diesel pusher, the depreciation is significantly lower. 

The engine’s longevity, the higher quality features, and other factors allow diesel pushers to hold their value better than gasoline motorhomes.

9. There’s More Storage In Diesel Pusher Motorhomes Than Gassers

We mentioned this briefly under number 4 above. One of the best things about larger diesel pusher Class A motorhomes is the storage. Sure, there are plenty of gasoline RVs with decent storage, but diesel pushers just have more. Not only do they have more interior storage space in terms of closets and cabinets, but they also have more exterior storage.

Storage compartments under the living space of Class A diesel pushers allow you to bring more comfort items, spare parts, and essential tools for maintaining your RV on the road.

10. You’ll Find More Living Space In Diesel Pusher Motorhomes

This goes along with some of our previous comments about diesel pushers. If you have a larger family or intend on being a full-time RVers, you will find that the added living space in most diesel pushers is a lifesaver. With more room to spread out and sleeping spaces like actual bedrooms, a diesel pusher is more comfortable. 

For full-time RVers, this added space also gives you the ability to have alone time or a quiet working space when needed. This can make a huge difference in the happiness factor for couples and families that travel.
