So If I have electrolysis working on the aluminum areas near a 110 fixture,
more than likely I have some bad grounding going on, correct?

If you are on shore power, the neutral and ground should be bonded at the main building panel. In the coach, neutral and ground on the main cable and forward into the coach should be isolated. (The generator source bonds neutral and ground but assuming you are on shore power) If there are errant neutral/ground connections in the coach, then the some of the neutral current will he carried by the ground, perhaps causing your issue.

Dean,
I was hoping that Emery would come in on this. As a marine engineer, we actually had a semester long course that was just about corrosion. As much as I understand, electrolysis is a wet process. I don't know where in the coach you would have any AC that was likely to be wet. If you have some place that qualifies and you have corrosion there, then it could be a grounding issue, or the related parts could just be on the wrong ends of the electro-motive table to play nicely together.

As I understand electrolysis, without constant moisture, it is not much of
a problem. But add salt and water to the equation along with direct
current, and it is a tough nut to crack. So if that fits your scenario,
probably best to eliminate all or some of those contributing factors.
Aluminum, magnesium, and a host of other "light" metals are particularly
prone to it.
