Buying Diesel vs Gas RV

When you’re considering buying a new RV, you’ll have to decide whether to buy a diesel or gas model. You’ll need to know the difference between these two types of RVs to make an informed decision when you visit a dealership like the Des Moines RV dealer. We’ll examine the pros and cons of each one to help you determine which is right for you.

Which is best, diesel or gas?

We’ll start by stating the obvious. The primary difference between diesel and gas RVs is that diesel RVs run on diesel fuel and gas models run on gasoline. The next thing you’ll need to know is that one type isn’t better than the other. The one that’s best for you depends on your needs.


When you visit the Des Moines RV dealership, you’ll find that gas RVs cost less to buy and maintain than diesel models. While the specialized parts and added labor associated with diesel models make them more expensive to maintain, they don’t require maintenance as often as gas RVs. In addition, gas costs less than diesel fuel

Many first-time buyers choose gas RVs because they can save money and still get a high-quality motorhome. But if you want an RV that offers the most luxurious amenities, a diesel RV is the best choice. While they cost more, they also retain their value longer than gas RVs.

Choosing a Gas or Diesel RV


Diesel RVs have better low-end torque availability than gas models. Low-end torque enables diesel motorhomes to tow and climb hills and mountain roads more easily than gas RVs. They’ll maintain speed when climbing without taxing the engine. The higher torque of diesel models helps larger motorhomes accelerate.

Fuel Economy

Fuel is expensive, and RV owners want the best combination of performance and fuel efficiency. You’ll pay more for diesel fuel, but if you’re taking a long trip, a diesel RV can be cheaper than a gas RV in the long run because it gets better fuel economy. On average, diesel fuel is up to 10% more fuel-efficient than gas. If you’re a full-timer who plans on doing a lot of driving, a diesel RV is probably your best bet. If you’re planning on using it for occasional vacations, a gas motor home may be the best choice.

Comfort and Luxury

Many higher-end gas motorhomes feature upscale amenities. However, in general, you’ll get more comfort and luxury from a diesel RV than a gas model. If you’re planning on spending a lot of time in your RV, you’ll appreciate the higher-quality interiors, the greater degree of comfort, and the attention to detail that you can get with a diesel motorhome.
