Just last week we returned from a short trip to The Big South Fork National Recreation Area. As we pulled into our subdivision I noticed smoke and diesel spray near the engine compartment. Our tow car was covered in diesel. After getting the Motor home to the Freightliner dealership in Nashville, it turned out to be a broken fuel injector line. We have close to 6,000 miles and bought this 2016 Newmar Ventana new last November. Just today I learned that this problem with Cummins is a regular occurrence. Fortunately the warranty covered towing and repairs.
