This is why I NEVER put plastic blocks under my stabilizing jacks. It may not be the best ground, but I want metal stabilizing jacks on dirt..

Metal jacks on DRY "dirt" does nothing at all to prevent shocks.

I understand and agree with what you are saying; however, metal jacks on dry dirt is a better ground than rubber shoes on dry dirt.

Not really.

In the whole realm of life laying metal on dry dirt presents a lot more resistance than a person or animals body will..

That is due to the fact that our bodies contain a lot of water plus minerals and salt, you then perspire which releases moisture plus minerals and salt onto your skin.. Takes very little moisture to make your body skin conduct better than metal touching bare DRY ground.

Not to mention, that metal tongue jack will be FAR away from say a RV door and the key here is the ground resistance will be extremely high between the jack and the RV door opening..

Your body WILL end up conducting MORE than the jack on dry ground in this case.

Dry dirt = extremely poor conductivity..

Damp dirt = better conductivity over dry dirt..

Saturated wet dirt = superior conductivity over dry dirt = MUD..

Properly installed 6ft ground rods at the service entrance = safest bet.

Ground rods are intentionally long and driven deep below the surface of the ground.

6-7 ft below the surface the dirt/rocks/minerals tends to stay DAMP, it is that dampness that makes ground rods work.

Metal on dry dirt does not equal a properly wired and grounded RV through the service entrance box as it is supposed to be done.
