  1 Question
Q: I RV and know how much other people hate when you run your generator because of the noise. How much quieter have they become? I am looking at the onan 12500w
by Linda Walsh from New Hampshire on August 06, 2012

A: I would say that sound levels have been reduced significantly over the years. The Cummins Onan RV QD12500 is one of your higher quality units out there and is rated at 68 db(A) @ 3M - Half Load. Per the product specs, it also meets national Park Service Requirements (60 db(A) @ 50Ft) for national park use and typical installation will further reduce sound levels.

If you are thinking about buying an RV generator from us, you are most likely replacing an existing generator which was probably an Onan.

Most customers coming to us have an Onan RV generator in their RV now. We always like the motto, "If it isn't broken, why fix it"? But in this case, yours is probably broken, which is why you are looking to buy a new one.

Did you have years of reliable service and creature comforts in your RV because of your old Onan RV generator?

Well,... more

"quiet Diesel"
While Onan advertises these generators as quiet, their cooling fans put out noise to the point that if you're in a quiet campground can be irritating. And servicing in the cabinet can be challenging.
