Altitude sickness is something some folks have and some do not. Now, what this means to you.
At that elevation I do not believe you will have a serious problem, but if you are one of the more sensitive you may "Notice" it. Odds are you will not but you might.
Your generator is more likely to notice it. But it has an adjustment.,
If memory serves I've seen 9,000 feet plus a couple of times with no problems (Crossing Confidential Divide, and on top of old Smokey and places like that)
I did have ears popping from the pressure change though.
