So it turns out that the generator doesn't like the thin air at 8000 feet. And after arriving home I found the altitude adjustment switch on the gen. Honestly my fault because I didn't look while abroad because we really didn't have to run the generator due to lower temps while driving.
When I did try to restart the generator once at lower elevation, it had problems starting and staying running. It threw multiple codes: code 3, code 36, code 33 (coolant temp too high), code 15 (under frequency), etc. Just odd.
And once home the step won't work. It's retracted about 3/4 of the way in. It's not the sensor. So now it's time to troubleshoot that. If it's not one thing, it's another...
