one thing, that thing is hella-loud and it'll never run your a/c.
i seriously doubt it could even run the microwave with only 1350w of regular power.
if you want to run the a/c, you'll need MINIMUM a Yamaha 2400w, which is advertised to run MOST 13.5 a/c's. you don't list what size/brand/model of a/c, so can't say whether the 2400w will run it. most likely you'll need 3000w of power to be sure to run an a/c.
i suggest you do some reading on decibel rating, inverter technology generators and power requirements for RV a/c's.
that way you can make an better choice for what you want it for.
if you plan on using it in a campground, look at inverter generators. not all are as expensive as the H & Y ones. the new Champion 3100w inverter generator is what i would buy if i didn't already have a Honda 2000w.
if you plan to use it boondocking or at motor races, then an open-framed non-inverter generator may be the ticket, unless you have sensitive electronics you want to run with it. the Champion 3500w is by far the best bang for the buck at around $300. but it ain't quiet.
Quiet costs more!
