Last time I checked the charging system (a couple of weeks ago) it was charging 14.6 v. and with the high beams on, blower motor on high the voltage was 14.4. I didn't think that that was out of line.

That sounds about right.

So there may be something that is waking up a system or two during the night, bumping the draw back up...
