RV "Hot Skin" and GFCI?

I would be questioning the complete electrical system. When the OP reset the GFCI, the hot skin went away. It is possible that the GFCI could be wired wrong or a connected load to it has an issue.

This afternoon I remembered another action I may have taken in between hot skin tests, something I did not think about when I wrote the OP: I may have reseated the shore power cable to the RV. I am confident the hot skin went away when one of the three actions were taken by me:

1) I reseated the shore power cable to the RV
2) I energized the 30A breaker on the pedestal.
3) I energized and reset the 20A GFCI on the pedestal.

Tomorrow am I will install the new input receptacle on the side of the RV. This coming week I'll be receiving the replacement card for the EMS and I will install that (I'll also be talking to Progressive Industries about the EMS not detecting whatever condition led to the hot skin issue). While the basement is torn out, I'll again trace and test the ground from the circuit panel to the chassis.

I'm not sure what else I can do. As much as I'd like to blame the pedestal, I don't have any solid evidence to support that. I've never detected hot skin before on the RV, but I can't say for sure it hasn't been present. However, I have done work in the past similar to what I was doing yesterday when I got shocked.

For the time being, I'll take the steps I described above and I'll do periodic hot skin tests. I can also ask the RV park to check the pedestal.

Other suggestions are welcome.

Thanks.
