As a GFCI can be used on a circuit without a ground, it must be labeled as such. And it can be a good solution for certain situations requiring a receptacle with a ground pin cavity. Yet it can lead to a Hot Skin condition when an RV is plugged into an ungrounded GFCI. While the GFCI might trip at 30-mili-amps of unbalanced current flow or less, it is not going to conduct that small limited current flow to ground. It can and may be felt if there is leakage current to the chassis or ground of an RV. And if a Hot Skin condition exists, it can be detected with a NCVT. It is unbalanced current flow that trips a GFCI, no matter where that current can flow and in most cases, current flowing to ground trips a GFCI to include the ground pin cavity connection of the GFCI, even If the circuit serving a GFCI is not grounded.
Well, putting water into a GFCI plug would certainly compromise the trigger point and even a tiny perturbation cause by plugging onto it would trigger it when otherwise normal operation would not.

He said he has a progressive surge protector. I cannot plug my Surge Guard into a GFCI protected circuit without it tripping it
Any Surge Protector with a MOV device is allowed to leak up to 3mA of fault current and still pass UL.

Great comment. You saw the open receptacle cover just waiting for some rain… 🌧️
