So, would it be a good idea when not connected to shore power to run a ground wire to a metal stake in the ground to potentially disapate any wayward electricity? Thanks
Had this happen in the house a couple years ago. Just the noise, not the boom! The conductivity of "Water" is quite variable depending on the mineral content. Pure H2O does not conduct at all and sea water is the other extreme. All public water supplies have some mineral content and will conduct some current but how much is variable.
Waiting to hear what you come up with for a test Mike. My idea is to plug the water heater or the RV into a GFCI protected circuit and run the water heater which should trip the GFCI if the element is leaking. I plug my RV into a GFCI protected wall outlet occasionally to verify there are no faults but I didn't think to run the water heater while doing so.

Any kind of fault current from a damaged electric water heater element should be sufficient to trip a 5mA GFCI.
