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.
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.
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.
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.
