Hello All; I also have a Honda 3000is. I initially bought it in 2005 for a much shorter 5th wheel (25 foot) with 1 air conditioner and a gas refrigerator. It did a great job. The air conditioner was a small one. I graduated to the Oakmont and thought, well, we do boondock so why no keep the genny. As fate would have it, we were at the annual Country Thunder Music Festival and boondocking. Side note: I do have the residential refrigerator. It was a bit toasty out in Florence, AZ., so I fired up my trusty Honda and had high hopes of it cooling down the unit for lunch. Wrong! A big wrong. The air conditioner (15K) ran for about 30 seconds, beeped, and the genny died. So, the 3000is will not run a refrigerator AND the air conditioner at the same time. I did not experiment by disconnecting the refrigerator and trying again. It just wasn't meant to be. I do have the spec's,

I love how I can run for 20 hours on a few gallons. I don't like hauling the fuel, but....
So there you have my own personal experience. Hope it helps in the decision making process.
