My Yamaha 2800I starts and runs my 15K BTU AC unit just fine. Even at higher elevations.
But just to be sure you will need two Honda/Yamaha 2K's and a parallel cable or a big old heavy 3K generator. Most people opt for the twins. Much easier to handle 55 pounds vs 135 pounds.
Nano, not sure where you live. I have a Honda at home. I thinking about selling it. I think it is around 4500 watts. I just bought a motorhome and will no longer need it. I live in Southwest Louisiana.

Camp every chance we get
We just bought a Yamaha 3000 watt quiet run generator. Runs everything in camper, Rockwood 2502s. It is heavy but my husband and i can handle it. Like the auto start, and it runs for 20+ hrs on a tank. It took us a while to choose 1 but after some studying, pricing and advise of other campers, it was best for us.
Nano, I was at Genreal RV in Birch Run about 2 months ago...they had a Dometic...very light says it will run A/C but I did not hear one run...maybe you can check it out...please post your findings...I'm interested in one myself, provided I don't get a Honda.

I have a 3500 watt Champion and it runs the AC fine. It is one of the El Cheapo Chinese brands and only cost $250.00. It is not very loud but if you are going to be using it in a campground I would go for something quieter.
