AGM is still lead-acid battery, so when it allows slightly higher charging rates, the flooded battery principals still apply.
Camper chargers went long way in last 20 years, so it depends what unit you have.
I found that when you heave deeply discharged battery - it will trip charging circuit breaker on the truck as well on converter on my 20 yo TC.
The automatic breaker will cool down and restore the charging, but that leads to very long hours to recharge.
That is why I am also carrying automatic charger with me, who monitors the battery stage and adjust charging amps.
For single battery you want 10 amp, for dual batteries 25 amp charger.
But beware that some chargers can have 15v boost mode, so better disconnect sensitive electronics for the time.
