Cummins Every Time - Motorhome

The Cummins ISC has built a reputation of delivering additional performance when a little extra is needed. With 8.3 liters of displacement and the extra horsepower and torque, the ISC is designed to provide the ratings and performance to deal with heavier loads and steeper grades. The ISC also utilizes the Cummins patented Variable Geometry Turbocharger (VG Turbo) and High Pressure Common Rail (HPCR) fuel system to provide enhanced engine response for outstanding driveability. The ISC has long had a low cost of ownership resulting from its exceptional fuel economy and long oil change intervals, but it gets even better because the VG Turbo eliminates the expense and maintenance costs associated with an add-on exhaust brake.

Plus, you get exclusive Cummins programs like Coach Care™ to meet your service needs as you travel across North America in your motorhome. All backed by the most extensive customer support network in North America.

The Holset Variable Geometry Turbocharger (VG Turbo) provides exhaust braking without additional add-on hardware in the exhaust system and eliminates exhaust brake maintenance. The operator activates braking by using the brake switch in the driver's compartment. ISC exhaust braking assists in stopping the motorhome while reducing wear on the service brakes.
