Cummins RV EnginesPremium motorhome buyers don’t settle for second best. That’s why the number-one choice for diesel-powered motorhomes is Cummins. They offer a broad range of power for every size motorhome on the market.   Plus, their 2007 engine and aftertreatment system reduces particulate matter by more than 90% without compromising performance, reliability or durability.

The Number-One Choice for Diesel-Powered Motorhomes

Designed To Deliver Every Advantage

Of all diesel engine manufacturers, only Cummins designs and manufactures the complete system from air intake to exhaust system totally in-house. It’s a process that gives us the ability to optimize every aspect of performance, on every engine from the ISB to the ISX.

Plus, our 2010 engine and aftertreatment system reduces particulate matter by more than 90% without compromising performance, reliability or durability.  The Cummins  lineup of engines not only meets EPA ’10 and CARB emissions regulations, they do so without compromising fuel efficiency, reliability or power.  Their fully integrated system includes a proven cooled-EGR subsystem, a high-pressure fuel system, the patented VGT Turbo, exhaust aftertreatment, combustion technology and advanced electronic engine controls, all designed to function as a single unit.

Cummins engines are built to give motorhome owners every advantage. That’s why Cummins continues to be the #1 choice in diesel power by an overwhelming margin.

  • ISX15 The XPI fuel system delivers a precise quantity of fuel at ultra-high pressures.  This, together with more robust electronic engine controls, enables multiple injection events per cycle.  Flexibility in injection timing increases fuel economy and performance while decreasing exhaust emissions.
  • ISL9 The ideal engine for larger luxury motorhomes. With power up to 450 hp and 1250 lb-ft of torque, the ISL9 can accelerate at any speed and quickly climb the steepest grades even when towing. The ISL offers a very strong engine brake for extra braking capacity and added driver control. With 20,000 mile (32,000 km) oil change intervals, the ISL saves money and time when it comes to maintenance.
  • ISC8.3 Built on a reputation of delivering additional performance when a little extra is needed. With up to 380 horsepower and 1050 lb ft of torque, the ISC8.3 is designed to provide the performance to deal with heavier loads and steeper grades.
  • ISB6.7 The ISB6.7 features a High Pressure Common Rail (HPCR) fuel injection system that enables multiple injection events per cycle for cleaner, quieter and more complete combustion.  The proprietary VGT™ Turbocharger has been improved as well for strong throttle response and dependability.
