Default Sharing ground rods

I am wiring a duplex house.
The services come to the back of the house and the meters will be about 12 feet from each other.
Can two separate 200 amp services share the same ground rods ? Each service would have a ground wire going to the ground rods.
Both ground rods would have two clamps on them.....

Yes they can, and without looking in my book, I think that if you installed 2 sets of rods, they would need to be bonded. I know your two services need to be bonded.

Wouldn't sharing the ground rods automatically bond them? I'm just trying to avoid smashing down 2 ground rods per unit

Install a 2/G meter socket and be done with it.

If I could I would. The rear elevation is funky.
They have storage sheds on the back of the units

No need to put two acorns on each rod, here's how we do it. Totally legal, no splices and bonded.

Would the rods be equidistant from each service? I am trying to edit this comment but I guess I am wondering why you would do that.

I would use the Cadweld one shots for the ground rod connections.
They are about $5 each
