I keep hearing references to a generator "dumping" excess capacity.
Does this mean that generator can be expected to use the same amount of fuel
whether unloaded or loaded to the max?
Is the situation different for inverter-bases generators? I've got an EU 2000,
which just ran 5.7 hours on a tank running a fridge and a freezer (235 and 350
watts respectively), about 600 watts total exclusive of startups -

No, it's just that a certain amount of fuel is required to keep the motor
turning at 3600 rpm.
Somewhat more load dependent. Some fuel is required to keep it turning at
the no-load rpms, which is around 2800 rpm.

A typical generator WILL use more fuel depending upon the load. For
example, a 5000 watt generator that uses 1 gallon per hour with maximum load
would probably use about one fourth that with no load. This may vary
greatly depending upon the quality of the engine etc.
An eu2000 will run (according to Honda) about 15 hours with no load. I have
ran mine for about 12 hours or more on a tank of gas with a small load. It
will run about 4 hours with one half load.
No, it's not. It's probably more in the neighborhood of around 600-800

Wrong. 2800 rpm.

If it's running at 2800 rpm at idle then what is it running at when at full
load? 5000 rpms? It's obviously running a LOT faster at full load.
