One of the best things I bought for my Motor Home was a battery monitor. About $200 with the shunt and wiring. I can monitor every .10 of a volt and amp going in or out of my batteries. I have the 2025 but they just released a new 2030 model with more features.
Now, if I leave a light on in my basement compartment, I can see the power drain and go turn it off before it discharges my batteries.

FYI - You need something to monitor the AC side too. This is one of the best surge protector and monitor on the market today.

To me, these should be standard equipment on all RV,s.
