You may have high resistance soil, and need more than one ground rod.
Code typically calls for three, wired together.

I think you are probably right.

A quick Google shows that multiple ground rods are often necessary.
Although I found the NEC calls for multiple rods only when a single rod
installation exceeds it says 25 ohms. And it seems that every other
possible reason has been eliminated.

I think I know what the problem is. In a house, at the electrical panel,
the neutral wire is connected to the ground. Your tester maybe assuming
this and that is why it is not showing a ground connection. Your generator
probably has a floating output (neutral not connected to the frame ground).
Which is why the tested shows no ground. This will not pose a problem when
using the generator, it is still grounded, it's just that the neutral is not
connected to ground.
