No argument with your posts. But, the question is, do you run the MH and Generator when in storage? Meaning, it will sit there 4 or 5 months. There is a big difference between "exercise" and "storage".
My Onan manual lists 3 operating situations, Break-in, Exercise and Storage. In the Exercise section it says, "If use is infrequent the genset should be exercised at least 2 hours each month at approximately 1/2 rated power". In the Storage section, defined as more than 120 days without usage, frequent running is not mentioned. They recommend doing several things but no running.
