That said, a generator capable of supplying 240v will always be preferred.
A standard, non-inverter generator generates 60Hz 110Vac by operating the generator coil at 3600 RPM. Any variance to the RPM directly translates to a change in the phase, or voltage, depending on the severity of the speed-up or slow-down. It's not possible to just use higher gearing to allow a small engine to run slower - a watt has a cost. The result is that the engine is running at a constant, higher rate of speed whether or not the power is consumed.
An inverter generator, on the other hand, involves electronics packages to deliver electricity at the rate of consumption; the full capacity of the generator will require the engine to run at its top speed; likewise, if no power is being consumed the engine will idle.
This Ryobi 4000 watt generator is considered "large" by inverter standards - and in this case is rather cheap - I am impressed. The Honda EU3000 is $2800. A Robin-Subaru 4000W (Fuji Heavy Industries) is $3100. Yamaha's 4000W is $3300.

So why is this Ryobi so much less expensive? One answer will be longevity and reliability, the other answer is the elaborate inverter technology itself - the power produced is cleaner, the "starting" power (capacitor dump) is delivered smoother, and so on. When taking a real close look at the output and how the draw is translated to engine throttle adjustments, the electronics packages are what makes the change more seamless.
For example, you're at the RV campsite and start making toast in one of those little oven things while the generator's running. The generator has to "recognize" that there is increased demand, and meet it by accelerating its engine. In between - a capacitor dump is involved - stored energy is metered out simultaneously as the new demand energy is produced. The Ryobi probably judders, doesn't switch as "cleanly" as the Yamaha, for example, but in the case of a toaster, who gives a shit? An air conditioning unit coming online won't really need a clean transition - but it wouldn't be a bad idea to not jolt it around every time it starts - also with the generator's cheaper circuitry internals.
If I had a $100K RV, I wouldn't be using a Ryobi to pass electricity into the battery charger banks and my sensitive electronics - my OLED TVs - etc.

I have the predator 3500 (3000 running) and this has more power on paper. In for 1 as a backup. Can't go wrong at this price
Also I'm assuming this is gas powered so how does this logistically work? You leave this outside running noisely in a power outage and then what, drag cords into your house for things you want to have power?
Sorry, ignorant as to how people use these besides camping or outdoor only uses.
How often would one even have to fill the gas?

Is that normal for inverter generators? Or is there something specific I should look for if I want something quieter?
I have not bought it yet. HD has is new @ 649. ebay and other have it 400ish + 80ish shipping.

For residential use, it gets more complex. Either you are running giant extension cords through your doors/windows/whatever, or you have a power inlet on the side of your house where you can simply plug it in just like an RV. Then you use a transfer switch or interlock to power circuits in your house.
But yes, it will easily power a fridge. I think most fridges come in at less than 1000W.
