I haven't had the coach very long but I do know the last 3 owners. I thought the same thing about the shavings being gone but I had to dig them out of a hole in the plug. Not sure if the previous owners may have not noticed them.
Thinking of running it a few hours and checking the plug again to see if I see any additional shavings.
I would think with that large of shavings the generator would not be sounding too good.
