Motor Home Specialist is advertising the 2018 Dynamax Isata for sale. The 2005 Chinook Glacier had three coach batteries in a basement compartment on a slide out tray and a 2,000 watt whole house inverter/charger.
Oh, I see. You are right. The Isata is back. At a glance it appears the compact B+ version is limited to the Sprinter chassis. The Ford based units are large conventional Class Cs.
3 batteries in a Glacier? Wow! It sounds like Chinook was trying hard to offer more than the others. They must be 12Vs in parallel to work. My personal experience is that a pair of 12Vs in parallel doesn't compare to the performance of a pair of 6Vs in series. If I had room for 3, I'd install 2-6Vs and have a blank space. I wouldn't know how the performance would compare to 3-12Vs, but I really like how the 6Vs are working for us. The drain is so very well balanced, and so the charge is too.
My experience with two different pairs of 12Vs wired up properly with balance in-mind, one battery would drain quickly while the other didn't contribute much. Over-all power reserves always suffered. Charging was always a boil-over mess with one battery being over-charged from that imbalance, and a full charge could never be achieved after year #2. I wonder what happens when having a 3rd 12V added.
