You should only have one ground rod everything should ground to it. So

I you have more than one ground rod then there can be standing voltage
difference between the ground rods which could be on the order of
thousands of volts.

Not true. The "Bible" on grounding is contained in Motorola Standard
R56. Chapter 4 deals with "outdoor" grounding and Chapter 5 deals with
"indoor" grounding. 518 pages total!

We drive ground rods (usually 2 joined together with ground rod
couplers) at each corner of our buildings and then bond #2 wire to each
set of ground rods, forming a circle around the building and buried at
24"-30" or so. Another #2 wire is connected from this ring (at one
point) to a single ground buss on the external wall of the building. We
build a similar ring around the tower base. The tower ring is connected
to the building ring. Page 102 of the R56 manual shows this...
