I replaced the battery because I have seen many issues with batteries on the forums, it wasn't terribly expensive and I just didn't trust the one that was in it as well as the one in it was not even the right type of battery, no vent tubes. I didn't replace it thinking it was going to be the fix to it all, the thought had crossed my mind, but I know the alternator would be the root cause of the issue due to the low charge voltage at idle.
I'm not arguing with you, I am very much agreeing with you
I am still hopeful that a good alternator rebuild or replacement will fix the issue, but I am not putting all my eggs in that basket. For now I have it backed into the garage where it will sit for the next several days while I am busy at work and going camping with the family. During this time I will figure out what I want to do with the alternator (rebuild vs replace) and pick up what I need, probably have that all set sometime next week.
