it ended up being a faulty circuit board. There was insulation that was making contact with the board and when the insulation got wet, it shorted out the board. I cut some insulation away and waterproofed around the circuit board and haven't had an issue since
It might be safe today, specifically; it is just condensation after all.
However, I am 99% certain that drain pan material inside A/C coils is not approved for potable water, nor is the PVC drain pipe.

It's probably not potable in any sense. I mean, I've drunk out of a garden hose a few times as a kid, but there's a reason they don't let you use those things for your RV potable water. The same would apply to A/C coils (anything on the coils could be in the water).
The larger issue will be that the line might start to fill with things like algae or mold. ...
