Remember that, due to their low internal resistance, AGM batteries accept more charging current at any applied charging voltage.
So .... if you have what you consider a "marginal" charger and/or alternator for camping off road for days at a time .... your setup would be even more marginal in this situation with wet cell batteries. So far after using AGM batteries for years everywhere - including around 8 years of the same set of AGM batteries in our RV - I see no disadvantage to them other than cost.
So my question is this. Will my system that puts out a maximum 13.6 volts be adequate to charge AGM batteries.
The short answer is yes. 13.6 volts is fine. Chargers with higher AMP output can charge them up to 10 time faster. It is best not to charge any battery at more than 13.8 volts unless de-sulfating or de-stratifying.
