Thanks for the "heads up" Gardner,
I've been researching the subject and learned quite a bit.

Like anything else on the internet there are a lot of opinions "out there"
here's a link to another RV forum where (John from Detroit)
answered most of my questions.

Battery and tire discussions are about the same. Combinations of facts and hear-say. As long as you do some research, understand the principals and keep an eye on things (preferably with eye protection) you should be fine. Specific gravity is a good method of determining how each cell is doing and can reveal issues that otherwise might not be apparent.

If you replaced the whole set a year ago and then one has a shorted cell, you should replace all 6? I don't think so! Maybe the new battery would work a little harder than the other 5 for a short period, but I would expect soon it would fit right in. It doesn't make sense to throw away 5 batteries with 5 or 6 years of life left to keep from working the 1 new one a little bit harder for a while.
Could buy a fork lift, har!

That's exactly what I intend to do,
a hydrometer reading on every cell once a month,
the reminder is already programmed into my phone's calendar.

I'm not ready to throw away what may or may not be good used batteries,
I'll never be a "purist" but I am here to learn,
before this tread I had never heard of the "issue"
if there is a significant "difference" I may keep them as a "backup"
by adding a third battery switch to separate them,
Not sure, I need to think on that some more.

When battery get older its internal resistance/impedance increases, chemical properties changed so when a fresh battery added in old batteries it could not be balanced with remaining old batteries in the string and according to series resistance calculation every different value in string will get different charging voltage, hence could not be charged or discharged evenly, resulting reduced performance of whole battery bank.
