Steve, our coaches are not that far apart so there is a good possibility it may be wired similar. The negative disconnect on mine only disconnects the house loads and not the inverter negative. My inverter fuse is in the same bay as the inverter, it is ~300amps with a cover that may be carpeted.
Stealing Richard’s diplomacy, battery voltage should be measured with one of the posts disconnected for an accurate measure. Mixing new and old is never a good idea (as you mentioned), and the only true determination (in my opinion) is specific gravity. Easy for you to do with non deep cycle types with removable caps. AGM batteries will not have caps. The rule of thumb for converting CA (not CCA) is CA/7.25. It’s only a guess but close enough to calculate capacity loosely.
If you want all loads disconnected, remove the negative from the string to the stud terminal on the bulkhead. When you reattach, you’ll likely get a big spark as the capacitor bank in the inverter charges up.
