Letting diesel rv sit for 3 months

Engine? No worry. But you might want to put a gauge on the tires once in a while. If nothing else it will mean less time airing them up for next move.

They shouldn't loose any air either. I have yet to need to add air after our winter storage, and yes, I do check them ! :B

With that said, one of my trucks tends to need air about once a year.

I am a retired farmer (after 40 years). Our combines sat in the shed for 9 months out of the year and some tractors sat for 4 months, all diesels and we had no problems, as long as the batteries were good they started right up when we needed to get them out. I would not worry about the time you are talking about.

Regarding the question on your generator, Cummins Onan recommends running their generators under load for 30 minutes every month, if not in regular use.

I do this with my gasohol generators for sure - Onan and a little Honda.

But is there something that can go haywire with the alternator itself if an Onan sits to long without exercise or do I have that wrong?

Running the generator dries out the generator end as well as exercising the motor.

Moisture is not an electrical component's friend.
