How to Discover Source of Hot Skin
My trailer is parked under a metal carport on a dirt pad covered with rock. It has been raining and the ground under the rock is damp or wet, depending on where you are under the carport. Last evenin...

When you have 3 conductors (Hot Neutral Ground) in close proximity to each other the 3 wires will have a capacitance between each other. The Ground conductor, if allowed to float, would try and rise to (120 / 2) volts because of the stray capacitance.
Also, if your RV is ungrounded and parked under a single phase high voltage (6000 VAC) line the RV chassis will float some where above 0.0 VAC.
In a perfect world with no faults and a good ground conductor the lesser the hot skin voltage is going to be but there is going to be some depending on circumstance. IMO
Another point, if there is any current in the ground conductor then there would be a voltage drop in the ground wire which might also show up as a hot skin.
What if the ground conductor were open circuit when you were lying under the RV but fixed itself when you started taking voltage measurements.
