S Davis,
Most of us just want the starter battery to be kept from discharging. An inexpensive continuous duty solenoid with a 200 amp rating will do that inexpensively and reliably (mine are 9 years old now).
I did add a trik-l-start to keep the starter battery charged for the long times between trips which has continued to offer perfect service for 7 years.
I was thinking it would be better using a dc to dc charger that can buck the voltage to properly charge the agm batteries, my truck charging system voltage sits at 14.2 to 14.4.
Don't agm batteries need higher voltage to properly top them off and or condition them?
