You are in an interesting situation. 
551.76 states that RV's, and RV pedestals, shall be supplied by an equipment grounding conductor (EGC), in no uncertain terms. Your existing wiring does not comply with this. However, since it is existing, and was likely installed prior to this code coming into existence, then I imagine the AHJ will probably be easily swayed into overlooking this detail.
I would consult with the AHJ and attempt to apply the normal rules surrounding seperate structures to these pedestals, 250.32(B).
If you could use 250.32(B)(2), then you would bond the neutral to the EGC of the circuit supplying each RV, and drive a ground rod (or two) at each pedestal per 250.32(A).
JMO,

- Right here.
I curious whether you bid this work, or whether it's T&M? I can honestly see this going either way, because I'd be hard-pressed to call this a "repair". You're basically replacing everything, except for the cable in the ground which happens to lack one conductor. I hate it when people give this sort of response, but I'm going to do it anyhow... I guess you'll have to check with your inspector.

I used to own several older code books, but in one move they were displaced.
I'm curious as to how far back one would have to reach to find where it was code comlaint not to run an equip ground.
Before I could be "swayed", I would have to be convinced the original installation was code complaint at the time of installation.

If I were the AHJ, I would require the installatioin of a grounding conductor. I see no other way to make this installation compliant. The ground rods will do nothing toward clearing a fault and article 250 prohibits the use of the earth as a ground faault return path. Your only hope would be to convince the AHJ that these are seperate structures fed by feeders and to use the neutral as the ground fault return path which would require connecting the neutrals and grounds together in each pedestal. The right way is to install new conductors with an equipment ground IMHO.
