AGM Batt on Trickle Charge?
I recall that AGM batteries are a bit different somehow, so I'd like to know what to expect. I'm thinking of getting a solar setup for tent snow camping. A Powerfilm 60w flexible panel/tarp, and a...

A battery totally out of use would be a candidate for a TRICKLE charge. Days and weeks and months out of service. No discharges at all.
You intend to put your system to use. Discharge and Charge.
At (80F) an AGM can endure 13.4 for trickle purposes
At (20F) an AGM would need 13.8 for trickle purposes
As cheap as PWM chargers are these days I would buy TWO tiniest PWM's, one for summer and the 2nd for winter. Leave the WINTER one alone, the voltage would be about right.
When the panel supports the battery in MAINTENANCE TRICKLE-ONLY charge I would adjust the PWM charger to the voltages listed above.
A fully automatic charge controller is about as likely has having a fully automatic wife.
