The new Honda 3200 generator looks to be the right size as it should run a 15000btu size air conditioner and the fuel injection feature should be just great. Have had two Honda Rancher ATV's with the fuel injection and never had a problem with either, they start great too.
Something to check out as an alternative now is the MXR3200 inverter generator that appears very similar to the Honda 3200 except I don't think it has fuel injection. It does have the 30 amp receptacle for the camper power cord. Search YouTube for reviews or just search MXT3200. The price is right at around $700 or less but search to see what pops up, Amazon, Walmart or whatever for the current price. Just noticed from pictures that the Honda 3200i does not appear to have the 30 amp outlet to allow plugging in the 30 amp camper electrical cord, sure hope I am wrong.
