Gas vs Diesel RV: Which is Better for Your Lifestyle?
Contents
Getting a motorhome is a great idea, but it’s important to know whether you should purchase a gas vs diesel RV. The diesel vs gas RV has been going on for some time, and the truth is that there are many factors that impact this decision.
The biggest variable that will influence your decision is the lifestyle you want to have in terms of your RV. So, let’s go over some of the elements you have to assess before deciding whether to purchase a gas or diesel rig.
Settling the Gas vs Diesel RV Debate
There is no “correct” answer when it comes to the debate on diesel vs gas RV models. Both of them have advantages and setbacks, so it’s all about the type of use you’ll give your rig.
Longevity
The first and perhaps most important variable is longevity: how long is the lifespan of a diesel RV vs gas?
Diesel engines are known to average more than 500,000 miles, whereas the lifespan of a gas engine is closer to 150,000 miles. This also means that diesel RVs have a stronger structural build because the engine itself will last for a longer time.
Gas vs Diesel RV Purchase Price
If you’re wondering which is cheaper, a gas RV or a diesel RV, the answer is clear: gasoline motorhomes are up to 50% more affordable than their diesel counterparts. For instance, a class C motorhome can cost around $65,000 when powered by a gas engine, whereas a diesel motorhome of the same category can cost more than $100,000.
Maintenance Frequency and Cost
Diesel engines require fewer trips to the mechanic on the whole, but their repairs are often more expensive when compared to gasoline RVs. Gas engines, on the other hand, will need more maintenance, but they are generally cheaper to service.
Class A Gas vs Diesel RV
In addition to the variables mentioned above, it’s also important to note that class A gas vs diesel rigs have a few additional considerations.
- DEF: Class A diesel rigs are required to use DEF or Diesel Exhaust Fluid, which adds an extra cost to these motorhomes.
- Brakes: Gas motorhomes employ standard disc brakes that are easy to service, while diesel rigs often have air brakes that can stop extreme weight faster.
- Driving Experience: The engine in diesel rigs is placed in the rear of the vehicle, which makes for a quieter and smoother driving experience.
Does the Type of RV Matter?
When it comes to choosing a gas vs diesel RV, the motorhome category plays a key role. Class A and class C motorhomes (to a lesser extent) are often diesel-powered, although gas versions of the latter are also very popular.
Families, which usually opt for weekend and short vacation trips, gravitate towards class B and class C models, so there are plenty of gas RVs available in this class.
