Go to YouTube, search on 'hot skin condition' and you will find several good videos explaining how this happens and how you can test for this potentially deadly - as in 'can kill you' - situation.
The SurgeGuard would generally protect from danger in a hot skin since it has a GFCI built into it. Any leakage from the hot skin to ground would trip it--and it ought to trip immediately if the ground lead were continuous through to the surge guard unit, even absent any leakage current. The others which lack a GFCI would not detect this condition.
Certainly a hot skin condition is very dangerous and should not be ignored (and is well worth checking for). To be honest, I don't entirely understand why RV receptacles aren't required by the NEC to have GFCI protection.
