Why Cummins Makes The Best Motor Home Engines

Aside from the obvious luxury amenities that come standard in most diesel pusher and Class A motor homes, there is another element that gets motor home owners excited…the power plant under the hood. Not only do we want an engine that can power through virtually any terrain, but we’re also looking for fuel efficiency, torque, a quiet ride, and perhaps most importantly, an engine that can be worked on by most truck mechanics and one in which parts are readily accessible when they are needed. In our opinion, Cummins has been consistently fitting that bill. With a nearly 100 year long history of producing high quality engines and components, Cummins is a leader in the diesel engine market, and has produced motors for nearly every type of truck that exists on the market today.

When it comes to motor homes, specifically, Cummins is so well respected for a multitude of reasons, but primarily for their durability. A well maintained Cummins motor could run for upwards of 1,000,000 miles if properly maintained. The other major plus is that there are certified Cummins mechanics nearly everywhere you go. So if you end up broken down on the side of the road, it won’t be long until you’re able to get someone to take a look at your motor and get your rig back up and running in no time. If you’re the type that has the know-how and likes to work on your engine on your own and find yourself in need of a part, it’s as simple as a quick Google search to find exactly what you’re looking for. There are dozens of authorized Cummins parts dealers throughout the country that can overnight ship basically any part right to your doorstep. The fact that Cummins has been in the game for so long and has produced so many motors and parts makes the availability of their products a great selling point.


Besides the convenience of getting ahold of Cummins parts or a mechanic, the efficiency of their engines makes driving your coach that much more enjoyable. When it comes to larger diesel pusher’s, Cummins’ ISL9 is where you’re going to want to be. This engine will push out up to 450HP and 1,250 ft. lb. of torque, so towing nearly any car or boat along won’t be a problem at all. In order to keep maintenance costs down, the folks at Cummins built this particular engine with fewer moving parts, which means less opportunity for breakdowns and failures in your motor. In addition to a more intuitive design, the ISL9 has an engine control module (ECM) that was built to enable multiple injection events which leads to a cleaner and quieter combustion. In English, that means this engine will have less mechanical issues, do better on gas than most diesels on the market, and won’t sound like you’re driving a tractor trailer down the road (although your engine will be equally as powerful and durable as most 18-wheelers out there).

Cummins also offers manufacturer warranties on parts and service, so owners can rest assured that they are purchasing a coach that will last them a lifetime.  All in all, if you’re in the market for a new rig, your best bet will be to choose one that comes with a Cummins engine. It shouldn’t be hard to find, most luxury motor home’s come standard with a powerful and reliable Cummins motor.
