"Regretfully, since you don’t own one of these newer generators, so you’re speaking “off the cuff” without any real "User" experience. In retrospect, I had both my old coach (standard set) and new coach (new protocol) in my garage for 3 months parked side by side for comparison of the generators."
It is very hard for me to believe that Cummins made major improvements to their quiet diesel generators and you are the only person that they told about it. I have been searching for news releases or reviews about these improvements and the only news that I can find from Cummins is about the new gas generators.
