Re: Hello, New U320 Owner

To address your original request on things to help you get to your intended destination I immediately thought of a potential failure the owner of my local Cummins dealer noticed when he walked behind my running coaches engine compartment. The m11 had an intermittent idle. Audible. Turns out the m11 uses a dual circuit cam position sensor. The oem part was potted in resin inside of a metal tube with wires coming out its end. Turns out oil intrudes into the potting material and shorts out the circuit. When both fail the engine stops. Replacement cam position sensor is a solid aluminum part. Later m11's I think went to a dual system where there are multiple locations where the cams position is sent to the ECU. Your sensor may or may not have been replaced. Or may not be oil soaked. Mine was at 2000 hours/106k miles. Two circuits are built in the one housing. The obvious hesitation in the idle was readily noticeable once one knew what to listen for. There was also an updated ambient air pressure sensor which is an external device with a quick plug in connection then zip tied to an adjoining pipe next to the motor.
If you want more power and better mileage and an easier to drive coach once you get to your end point please feel free to post your interest here or message me.
Long ago I was a Foretravel stores sales manager and was a very hands on guy as far as improving the product. You have one of the finest engineered coaches made. Almost endless upgrades are available to make your coach more fun to use and to work even better.
