If there is one hot topic on the RV forums online, it is the question: gas vs diesel RV – which is best? And there are many opinions on the subject.
It seems that many RV owners think that whatever engine they have is best. But it’s just not that simple.
RV manufacturers still make RVs with both gas engines and diesel engines. And they both sell very well.
So there are those who benefit in some way from the features of each engine. And that means that there are pros and cons for both gas and diesel engines.
I am going to try and provide a solid list of these pros and cons for you now. If you have even further points of your own to add to this list, please do so in the comments below.

- They are powerful. In some cases, very powerful. They can climb a steep grade with ease because of the engine’s lower torque.
- Diesel engines have exhaust brakes that will make going down a steep grade much easier too. This saves your wheel brakes from overheating.
- Diesel engines are very good for moving heavy weight. So you can have large appliances and more luxury features built into diesel pushers.
- More living space. Since weight is not such a problem with diesel engines, the RV can be bigger and longer.
- The noise level while driving a diesel pusher is much lower. This is mainly because the engine is way back in the rear of the RV.
- More storage. Most diesel pushers have large storage compartments. Some are often even pass-through bays that make storage a breeze.
- Diesel engines usually last much longer before needing to be rebuilt. In fact, you will probably wear out the RV before the diesel engine itself.
- Diesel pushers usually have air ride suspensions. So they seem to just glide down the highway.
- They also can tow much heavier vehicles due to the powerful engine as well as the beefed-up suspension and braking systems.
- Diesel pushers also hold their value much better than gas-powered RVs.
Diesel Pusher Cons
- The cost to buy! Diesel pushers cost a lot more when new and used. If you are on a budget, this may be a big issue.
- They also cost more to maintain. It’s not necessarily a lot more, but there is more expensive maintenance that goes with these engines.
- Rebuilding or replacing the engine is a major expense. Again, it doesn’t happen often, but when it does, get out your wallet!
- A long diesel pusher will have more difficulty getting into some national parks and boondocking spots as well as some fuel stations.
- Diesel fuel costs more. Although, if you get a good diesel fuel discount card the difference between fuel costs narrows considerably.
- Since diesel engines require a qualified diesel engine tech, finding repair facilities for them is not as easy as gas engines.
- Since diesel engines require the use of DEF (diesel exhaust fluid), it is another liquid that you have to keep on hand for every fill-up.
Gas vs Diesel RV – Gas RV Pros
- They are less expensive to buy! If you want to RV full-time, the entry expense can be high. But gas-powered RVs make it easier to get started.
- They are less expensive to repair and maintain. All those extras and luxuries that go with Diesel pushers cost more to keep up.
- When it is time to repair or maintain a gas RV, there are a lot more places to choose from for RV service.
- Since they are smaller, they can often fit in more campgrounds and national parks. And finding boondocking spots is easier too.
- If you have some kind of auto mechanic background, you will probably be able to do some of the repairs and maintenance yourself.
- Gas is cheaper than diesel. So if you are on a budget, this is an area where monthly savings can be had.
- Getting in and out of gas stations is usually much easier because the rig is not as long and cumbersome to move around.
Gas RV Cons
- They don’t have as many extras and features as diesel pushers. All that gingerbread requires weight management that gas RVs don’t have.
- They are not quite as comfortable as diesel pushers while going down the highway. But the newer gassers are much better at this.
- The engine does not last as long and will require rebuilding much sooner than a diesel engine.
- They don’t retain their value nearly as well as a diesel-powered RV.
- They have less storage capacity. Again, this is because diesel engines can push more weight. That’s why truckers use diesel engines.
- They can’t tow as much. There are plenty of vehicles that they can tow, but you won’t be able to tow the heavy ones.
- They are noisier in the cockpit. Since the engine is right there next to you when driving, the noise and heat is greater, especially at high RPMs.
How To Decide Between A Gas VS Diesel RV
When considering a gas vs diesel RV, it’s a lot to think about. But essentially, a lot of the differences comes down to cost.
If you have plenty of funds available for purchasing and maintaining your RV, a diesel pusher may win out. But if you are on a budget, a gas RV may make a lot more sense.
If lots of luxury appliances and items are very important to you, then maybe a diesel pusher is best for you. Then again, maybe having a smaller and more manageable RV that can fit in smaller spaces easier is a high priority. In that case, look seriously at gas-powered RVs instead.
The good news is that either one will be fine for enjoying the RV lifestyle. Many RV owners full-time in either a gas or diesel-powered RV while enjoying the RV lifestyle immensely.
And either a diesel pusher or a gasser RV will take you where you want to go in your RV travels equally well.
Regardless of what you may hear from other RVers who have already made this decision, the answer is not clearcut.
There are plenty of diesel powered RV owners who are very happy with the choice they have made.
But there are also plenty of gas powered RV owners who are also happy with their decision.
So there is no right or wrong choice between these two types of motorhomes as far as RVing is concerned.
Just balance your needs and concerns and make the choice that will fit your situation best.
