1, The positive 12V powering the battery monitor should be fused.
2, Be sure none of the 12V appliances are self grounding. Or if they are be sure their mountings are isolated from chassis.
If one of those appliances were self grounding, your battery cutoff is effectively bypassed.
Were I building this and ignoring for now the merits or not of the rotary switch...
I'd not have battery cutoff on the negative. Putting instead between battery and positive bussbar.
Or more likely, I'd simply use the main battery circuitbreaker as the battery cutoff. The 12V supply for battery monitor, I probably put it on the load side of battery cutout also.

My trailer project is reaching a critical phase where planning and drawings are transformed into solid reality. It is certainly exciting but a bit scary to delve into a project with so many aspects that have to be right for it to be useful, comfortable and safe. Before I start stringing wires and before my time to return items elapses I wanted to post my current and hopefully my final electrical schematic for the group to review for errors and misunderstandings. I do understand that there are many ways to make this work. I am looking for outright errors or potential dangers in effectiveness at this point. Thank you all.
