The requirement for ground rods at a separate building was in the NEC when I started in the trade in 1978, and likely many years before that.
This is similar to your earlier thread and the answer will be the same if it is the same question.
ground rods other than point of service.
My local jurisdiction is requiring 2 additional ground rods installed to outbuildings fed form an existing service. eg. a metal building is set on a property that already has a house on it. the house has its service and we run from a panel to feed the building with a 60 amp sub feed. wouldn't...

the situation is a main panel containing 20 spaces and feeds rv sites. a 100 amp sub panel was added about 110 feet away from the point of service. all of which don't attach to any buildings. the new 100 amp sub panel is free standing and will service 3 rv spots as well as a pole barn made of wood. again there isn't a building for any of the panels.

no buildings involved. all equipment (service and sub panel) are in a rv park
That has nothing to do with the panel being detached from the building with the service, if the panel is standing alone it needs the GES

I agree with Roger. The panel needs a grounding electrode system. That usually means 2 ground rods.

250.32 says "buildings OR STRUCTURES."
I would think the subpanel is mounted to some type of structure.

What if it's mounted to a tree?

in that since every rv location would require a GEC. each rv site has a panel with single 20 single 30 and 2 pole 50 breakers. that would put 300 ground rods in just so satisfy that.
Sounds like somebody is going to get a good work out.
