Ann Cat,
Hmmmm ... you mention regarding your Onan - "have to set altitude every time".
I've never adjusted the altitude setting on our built-in Onan generator regardless of what the manual may or may not say. It has always started right up and "run fine" at sea level or up in mountains. I wonder what the downsides of doing this were/are?
(However, from experience I know what goofing up and running an engine too lean, too long, can do to it. So I guess that my Onan may have only been run too rich on a lot of our motorhome trips.)
I had run it from sea level to around 8000ft. My manual says that running it with higher altitude setting at low altitude will damage the generator. Not sure about the other way, but its supposed to sputter, surge, run poorly if altitude is high and isn't set in the generator. May be its not noticeable with newer generator in top shape.
