Doubt you'd need a 7000 unless your running both AC units. The Honda EU3000iS is a good balance of power and quiet and you really needed more you can buy a second and run parallel.
Run that 7000 in a campground and you're neighbors might sharpen their pitch forks ;) I had a guy running one of those contractor grade units. I asked nicely to move, but he didn't care. Went to camp host and he went over generator hours, I agreed but asked that he run it on his side of the RV not the side I was on. Bingo. He moved it, never heard him run it after that - deafening.
