Onan Micro Generator 2800 same as 30 amp shore power?

OP shows to be from San Diego. If OP is not at home and is high up in the mountains, the generator will loose substantial ability (output) with each increase in elevation of 1000 feet. The Onan manuals give the exact amount and I don't recall the amounts, but it is much larger than I would have assumed.

Just something for all of us to keep in mind. I found this out the hard way....camped for a week at 10,000 feet!
