I hate to say it but I have this generator and it is money. will power your 15k btu, and everything else. pretty easy to move around, I can easily lift it and it fits under the hatch. I highly recommend. plus 699? hard to beat. its very very quiet too. no complaints from me so far. By the way you can parallel them up and have 6000 watts of power for $1400!
