Ok.

But is there any possible/probably correlation between that specific breaker and my full loss of 12v? Is there a specific way to test this on my meter?

I'll definitely replace the breaker for the hydraulic system, but if I still can't turn a light on without shore power, I've got more issues to resolve. (This is a fairly common occurrence when I start 'fixing' things.)

CnS, thanks for the Lippert doc.
