Have you had it the entire time or did you buy it like that with low hours.
I am curious because you never said; but what is it doing or not doing; and when did it start or stop?
That genset avg 8 hrs / year. I am only averaging 75 hrs per year and I am trying very hard to double that
It is easier said than done. When you do get it fixed; things to make the Genny easier to use besides the romantic escapes
1. Buy or use the AGS, let it work for you and keep things going. I have never had to prime my genset because it runs so frequently.
2. When it has started, let it run at least 10 minutes before shutting down
3. Don't hesitate to turn on to use ACs if coach is warm, I can't tell the difference in gas cost. I know it is a little more, but I can't measure any relevant amount.
4. Put in Quiet Time mode at home and even on some trips when boondocking, you will get at least 2 hrs / day.
5. Changing my own oil and filter also tends to make me want to use it after I have dome the work servicing it
Good luck
