Induced power from nearby lines??

This is a mute point but I believe the RV (isolated from ground by rubber tires) is a capacitative plate located between the high tension lines and ground. This conductive plate (RV frame) becomes a voltage divider between the high tension wires and ground. Fortunately the tires have a much higher dielectric value then does the air (between the RV and the high tension wires) thus the 15 VAC RV to ground is not excessive, troublesome but not excessive.

What I am implying is that the measured VAC is not an "induced" voltage but a capacitatively charged voltage on the RV chassis. It is the same phenomenon you see with a length of ISOLATED ground conductor sheathed/bundled together with the same length of 120 VAC Hot Wire and a 0 VAC Neutral wire.

An electrostatic field could be generated if the wavelength of the receptive device (camper) is long enough to generate standing waves.

A magnetic field generates a current, and a current generates a magnetic field, so induced voltages would require a path for current flow, so we agree.

An electrostatic field also requires a path for current flow.

This would mean the ground would have to act as a conductor (definitely possible), the tires would have to act as an insulator (definitely possible), and the metal camper structure would have to act as a charged plate (possible but only at a very very low level due to minimal standing wave action) pulling charge to/from the power line.

If your hypothesis is true, grounding the frame would definitely draw a good arc, which would also be true with induced voltages.

Interesting possibilities both of which can be tested for.
