AGM Batteries storage maintenance charge
Two Trojan 6V AGM batteries in series (12v). If we put them into 6 months storage fully-charged what would you recommend as the minimum amps for a charger/maintainer? Thanks!

I wouldn't. For three reasons:
Everybody needs a small battery charger from time to time.
A true "tender type" charger will drop down to OFF or float when they are fully charged and ramp up only when needed. If that is never needed during the storage time, it is little different than nothing being connected at all.
I think that checking the voltage of each battery after sitting for 3 months or so will give you a VERY rough idea of it's condition. If it is still 12.8 or above, I'd attach the tender for 48 hours or so and check again in another 3 months.
If less than 12.8, then I'd measure each one.
The most common automatic maintainers are rated at 2 amps and that is plenty for most people.
