I don't understand your Trickle Charger measurements. You originally measured zero volts from bolt to Earth with shore power disconnected, then measured again and this time found 18 volts between bolt and Earth with shore power disconnected. How was the Trickle Charger involved in the two measurements?

This really surprised me too. The trickle charger +/- leads were connected to the +/- terminals on van battery (the one that starts the engine), while the shore power cord was unplugged. In this config I measured the 18V to shore power GND at extension cord (which is on same AC circuit as shore power plug). In this config, I can feel a tingle on wet finger when standing on the ground. In theory the trickle charger should only provide DC volts, so it's unclear how it's injecting AC volts to the chassis GND (the bolt).

Is the trickle charger a 2 prong or 3 prong cord and plug?
