I think that batteries (after maybe oils and tires) are the costliest "expendable" components of our EVCs! Anything we can (within reason) do to increase their performance, dependability and service life is worth exploring. If the stock onboard charging system for the EVC coach battery is incapable of properly charging a AGM (which is otherwise probably a better battery for that job) then it is important that we know about it.
I have to use a electrical medical device every night (a CPAP) and I need to know my coach battery will work the way it is supposed to! I was thinking of replacing my standard wet cell deep cycle battery (which has been weak lately) with an AGM, but now I am not sure. I was planning to also put a solar recharging panel on my pop-top, but I assume I would have to put some sort of isolating device to the coach battery charger - that whole circuit is a bit confusing.
If we can have 400+ messages on ATF replacement, then 50 or so on batteries is not too much ;-)

As Pat pointed out if everything on a vehicle of any kind was the very
finest it would take all the gold in Fort Knox, if there's any left, to buy
it! I own a 17 foot Casita travel trailer and battery types and care are a
constant topic on trailer groups too. Most people end up replacing the
standard wet cel battery with another of the same type. The extra cost does
not warrant the better agm battery for most people. But those that do get
them buy expensive shore power converters to keep them charged roperly. Both
can easily cost $400 then some opt for two batteries. There is no perfect
battery!
Let's get back to tires or maybe fuel lines :=}
