If the coach and the chassis batteries are the same type, then no issues with merging them and letting the charger do it's thing on all of them. If you do that you still have the possibility of leaving yourself stranded.
Reread the post. The charging profile, specifically the voltages for bulk, absorb, and float is what you are looking for from the manufacturer. SOC for any lead acid system, including AGM, should not be taken below 50 to maximize battery life.
People use AGMs for start batteries. It works, but standard lead acid batteries work slightly better. If I had your setup, I would move the AGM's currently in the chassis to the house, and replace the chassis batts with standard lead acid starting batteries.
Did you ever figure out why your batteries died at Tom's. You posted about the problems, and then crickets on the resolution.
