Image source

There is no wrong answer in choosing between diesel RV and gas RV. Several factors can affect your decision, such as your financial status, travel frequency, floor space needs, maintenance, fuel economy, and the like. However, learning the difference between the two can help you make the right decision that suits your RVing goals.

Essential Questions You Should Think About

The main difference between diesel RV and gas RV is their engine. One is powered by diesel, while the other is powered by gas. However, before we could dive more into more details about diesel RV vs. gas RV, it is best to look into the following questions first to help you choose between the two:

Travel Style

  • Are you planning to be a full-time RVer?
  • Do you plan to be RVing part-time?
  • Are you planning to go to flat areas or mountainous regions on your RV?
  • Do you plan to tow the RV?

Fuel Economy

  • Are you planning to be an RVer to save money on vacations?
  • How vital are infrequent fill-ups?


  • If you plan to become a full-time RVer, how do you want to do regular maintenance checks for your RV?
  • If you plan to become a part-time RVer, do you want to schedule your RV maintenance checks when your RV is in storage?

RV Size

  • Do you plan to have a smaller RV (25ft long or less)?
  • Do you plan to have a larger RV (38ft long or more)?

Diesel RV vs. Gas RV: How They Compare

Your RVing plans will have a significant impact on your decision to choose between diesel and gas RV. As you look around for what type of RV you would want to buy in the future, you will find out that gas RVs are cheaper than diesel RVs.

Even the high-end gas RVs will come out as cheaper than low-end diesel RVs because diesel RVs keep their value better than gas RVs. Hence, if you want a low-cost RV upfront, a gas RV is a good option for you. However, if you prefer a good investment value, purchasing a diesel RV is the way to go.

If you want to travel frequently using your RV, it will help to know that diesel fuel is more expensive than gas. Moreover, diesel is not readily available compared to gasoline. On the bright side, diesel gets better fuel mileage than gasoline. This means that you don’t need to fill up the tank much often.

Diesel engines last longer than gas engines. That’s why diesel RVs have a high resale value. Moreover, diesel RVs don’t require full maintenance as often as gas RVs. But if they do, you have to look for a professional because diesel RVs are complicated to work with.

On the other hand, although a gas RV requires more maintenance, you can work on it by yourself. Also, maintenance for this type of RV is much cheaper. If you need a part for a gas RV, you can easily find one at a low price. However, diesel RV parts can be challenging to find and can be expensive.

What to Know About RV Financing

Purchasing an RV is a perfect idea for those who want to live their lives on the road. However, for some, it is quite challenging to buy and own their dream RV. Here are vital steps you would want to consider in financing your RV:

Set a Budget

It is essential to know what kind of RV you want for you to decide on the budget. You can get a towable pop-up camper RV for about $5,000. However, if you want a high-end type of RV, it may cost more than a million.

It will help if you consider how large you need your RV to be. A smaller type of RV is much cheaper and easier to park than a large one. But, if you plan to go RVing with a large family, a small RV might not be the best choice.

Setting a budget is vital since you don’t want to buy an RV you can’t afford. It would help if you also consider the repayment terms to help you decide on the budget. RV loan terms tend to range from 10 to 20 years, depending on the loan.

A shorter loan term has a higher monthly payment but can be paid off quickly. On the other hand, a longer loan term has a smaller monthly payment, but it may cost you more in interest.

Save for the Down Payment

Most RV companies tend to ask for a 10% down payment, while many require a 20% down payment of the purchase price. On the bright side, giving a larger down payment will lower your monthly payments. Hence, it is essential to prepare for a sufficient down payment since RV companies require it.

Check your Credit Status

The higher your credit score, the more chances you’ll end up with RV loans that have favorable terms and interest rates. You need to check your credit status to solve discrepancies if there are any. Also, if you have a low credit score, make ways to improve it in the meantime.

Decide on What Type of Loan You Prefer

Consider whether you should get a secured vehicle loan or an unsecured personal loan to purchase your RV. A secured vehicle loan tends to offer lower rates. However, lenders may require you to pledge the RV as collateral. On the other hand, an unsecured personal loan can offer quick funding and pre-qualification that does not risk your RV from repossession if you fail to repay the loan.

Shop for Different Lenders

It will help if you shop for lenders. You can look at your local banks, credit unions, or online financing companies, such as My Financing USA, to help you with RV financing. Comparing lenders will help you save money plus get you the RV you want in the most convenient way possible.


A diesel RV is not considered as better than a gas RV, or vice versa. The right option depends entirely on your RVing goals. Hence, in choosing between the two, consider your future RV plans.
