My chassis batteries are older than yours, wondering if I should plan for replacements before they die "on the road"?

After getting them isolated from each other and the chassis..... the (still healthy) battery showed 12.5v and the hot one showed 11.2v.
It appeared that the bad battery has shorted a cell and lowered the combined voltage of the two so that the generator sensed the need to charge the chassis batteries.(I had the Gen in "AUTO mode" so that it would start when charging was needed) With the one shorted cell, that would result in overcharging the remaining 5 cells of the bad battery - thus boiling what was left of the electrolyte and the resulting sulfur stink.
Once the bad battery was isolated, the chassis battery was not being overcharged, it stayed between 12.6 and 13.1 the remaining days - and started the chassis w/o any issues to head back home.
Our Seneca is a late-year 2015, Like you- I just replaced the house batteries that have date stickers of 8/14. I was being proactive by changing them out early... and I now think that I should have replaced the Chassis ones at the same time.
On another side note: The AUTO mode on the gen works really cool... We used the Inverter a bunch over the 11 days, when the battery charge became discharged to the 2/3 bars on the control monitor - the Gen started up and charged the house batteries.
