you have two basic choices, do you want cheap or do you want quiet?
cheap is loud and quiet is expensive.
the Champion 3500 is the winner for power and price.
BUT it's an open-framed construction-style non-inverter generator.
it's perfect for boondocking or at the motor races.
BUT it doesn't belong in a campground, unless your neighbors are far away. nor are they good for sensitive electronics.
an inverter generator will be way quieter, use much less fuel and will work fine with sensitive electronics. Honda and Yamaha are the Gold Standard.
but there are a number of new Chinese-made ones that can rival in low decibel ratings and power, but are much cheaper. Champion makes 2 different models, the 2000w and the new 3100w. Kipor was the first Chinese made one that went up against the Red and Blue teams.
Boliy is another one that has been around long enough to prove itself.
all the other Chinese made ones haven't been around enough to show whether they can compete.
