Choosing a new motorhome is one of the most exciting things you can do, but there’s more to think about than the color of the interior and the number of beds. Selecting the right type of engine to propel the RV is one of the most critical parts of the process, though the decision boils down to one of two choices: Gas or diesel.
Manufacturers offer both gas and diesel options because they appeal to different buyers and hit different price points. While they might seem similar on paper, especially regarding engine size, there are significant differences between the two fuel types that can impact your rig’s capabilities and what you’re able to do with it out on the road.
Towing
Gas engines are quite capable when it comes to towing, but they almost always fall short of the numbers from a comparable diesel mill. Diesels produce more torque, allowing the vehicles to tow heavier loads, which is important if you have a toy hauler or need to pull a second vehicle behind your motorhome. Most are turbocharged, making them better at towing in high altitudes. They also tend to be more durable after a life of heavy towing, so that’s something to consider.
Fuel Economy
Diesel is more expensive than gasoline, but diesel engines sip fuel compared to others. That fuel economy can help overcome the price differential between the two. However, it’s also important to note that diesels require periodic DEF (diesel exhaust fluid) refills, adding more to the cost.
Maintenance Costs
Gas engines are cheaper to buy and cheaper to fix. While diesels generally last longer than comparable gas engines, the maintenance costs to help them reach that longevity add up faster. Depending on where you are in the country, it may also be difficult to find an experienced diesel mechanic, though many traditional repair shops offer service for both fuel types.
The choice between gas or diesel for your next RV or motorhome comes down to your needs and budget, but don’t feel like you’re missing out if a lower-priced gas model is your best option. Today’s gas engines are surprisingly efficient and durable, and most offer the capability you need to tow or haul almost anything in your fleet.
