Battery disconnect
Our camper does not have a battery disconnect. And I have never had occasion to want one. When do you use yours? (And don't say "When you want to disconnect the battery.")

I added a shut off switch to mine and decided to add one that supported two batteries and added a second battery in a battery box in the wheel well. Since I don't have matched batteries I use one battery till it starts to get low and then switch to the other. I never run them in parallel but could if I ever replace both batteries at the same time. I would still probably use them one at a time since I know how much reserve I have left when I switch batteries.
