We use this primarily for running the camper when there is no electricity at the site. Ran the A/C unit (13,500 btu) a 2 slot toaster and the water pump all at the same time while charging the battery without missing a beat. Ran about 10 hours a day for 3 days and went through just about 5 gal of fuel. It is a louder unit than my in-laws 3500 watt Predator generator but not obnoxious at all. I would buy another one in a heartbeat if I had to.
Super quiet & powerful. Get this one... quieter than stated. We've had 3 Firmans for about a month... so far so great! We tried a competitor's generator & returned it as it was much louder. Only con is drain plug for oil is in awkward spot, and spills everywhere inside the generator & then leaks out making a mess. Having a drain leading to one draining spot/hole would have made sense.
Pros: Plenty of Power when needed, Very quiet - quieter than the smaller version.
I don't know if I would buy this product again as I have not

I bought this to mainly have a standby alternative power to my two bay garage shop. To raise a 10,000 pound hoist, lighting for the main house and travel trailer use in the bush camping.
Bought for house backup power(only to keep fridge and freezer running), and RV camping. My trailer has a 13.5k ac and the overload light will momentarily flash on when the compressor would come on. Used the gen for a week camping trip and no issues. Runs well, starts easy, and will power everything in the trailer. I did add a soft start to my ac and it made a real difference in the load on the gen. I can run this in power saver mode now and no more overload light and better fuel usage. I do like the fact Firman includes oil, funnel, and cables for battery charging.
