That's a very strange looking ground rod (with the screw-in pointed tip and the dowel in the middle). Why not just show a conventional 8 foot long (or 10 foot long) copper plated ground rod?

Interesting letter. Worrying about the ground rod is not something thats crossed my mind at a campground, or even my house. In some labs I've been in they have run #4 copper wire around the perimeter bolted to the building steel, but that was for different reasons than a a ground rod.

So I'm wondering. What would happen to your RV if the campgrounds ground rod was bad or missing? As you mention the neutral/ground bond is whats important. A ground rod is not going to trip a breaker even with a dead short (120v/25ohm = 4.8A). It could drain off static charges. As I understand it the purpose of a ground rod is lighting protection.

Thanks
