Remember to reset it when you get back down off the mountain. Might want to have a post it note somewhere to remind you.

Onan makes a diesel in the 3k range then they go up to the 6 kw size.

Thanks for the information.
The problem is a combustion issue. Your generator is a newer product, using a 2 cylinder engine and is configured differently from the more common 6K to 8K generator configuration.
You mentioned the air filter has been changed. How many hrs. on the generator?
Have you had any fuel issues with the coach? Water or dirt in the fuel.
Have you run any injector cleaner through the system?
Fowled fuel injector, carbon build up in the exhaust system and any restriction to the air flow through the engine can cause a combustion problem, that is more prevalent at higher altitudes.
The fuel and air filters on you unit are accessed directly under the unit by removing different access covers.
The spark arrestor clean out is in a slightly different location. Look in your Owners Manual for the proper procedure if you are a DIY person.

The smoke is white.
Thanks for the information.

The things that come to mind are. Fuel filter, Fuel pump or restriction in the fuel line, this could be do to the fuel line being crimped in some manner or some thing in side the line itself.
Just got to ask if this has happened when you are at altitude in the last few mouths or has been an issue from the day you picked up the coach? Not allot of hrs. on the unit.
Wondering if something like a very small air leak in the fuel line somewhere.
Interesting because it works at lower altitudes with no smoke,, one would think the white smoke would be more prevalent at lower altitudes because of greater air pressure.
