Excellent article. Will also check for that just in case.
Re-bonding seems to have fixed it, but perhaps the now solid ground is masking my problem. Will let you know.
If the Neutral and Hot were reversed at the campground, the power conditioner should have alerted me with a "red" indicator light though...
Also you would have 120 volts between the Neutral Buss and the "Ground" (green/bare wire) Buss if the Neutral/Hot was switched (Reverse Polarity) at the campground (or at the socket - in the article).
There was less than a volt when measured between those two; yet 39 volts between the frame and the dirt outside.
