Not every generator is created equal, even though they state the same Watts. I have a Micro Air Easy start that I added to my 15000BTU AC unit. I can run it with one Honda 2200i at 6,000 foot elevation. Sea level I can also run the fridge with the A/C on. I will admit that at 6,000 feet elev. everything is on propane and I have solar hooked to the batteries to minimize the need of charging. I also have a Honda companion I bring to the high elev. trips, so we can run the TV etc. with the AC on.
Good article on generators:
