Battery Disconnect Switch

I am attempting to learn about batteries, converters and other hardware related to my motorhome's electrically system.

So--

Relating to the house batteries, there are two Grp27 in my motorhome, and the associated 'battery disconnect switch':

Am I correct in understanding that when I turn the 'battery disconnect switch' to off the house batteries are completely disconnected from the entire house electric circuit?
&
In so doing I will have eliminated all parasitic drain (except the batteries internal drain)?

Thank you

Not always depending on the RV.
Are there any smaller wires connected to the battery besides the big cables?

For example, I know one thing on mine is that the electric steps still work.

No other wires except the big ones on the battery(s).

The electric steps do not work when the switch is off. There is a safety feature to them in that when the engine is started and the steps are extended they will retract regardless of the battery switch position I assume that power comes from the chassis not the house battery.

I only have one large positive and negative wire going to the batteries and with my switch off, my landing gears still works. Also the co2/carbon monoxide is on. And the entry light when the screen door opens. That's pretty much it. Jerry

With some more poking around I found that with the disconnect off the slides still work. My co2/carbon monoxide goes off and everything else goes off as far as I can see now.

There are only the two "large" wires to the batteries - red and black - the black is attached to the battery case itself, the case of course is attached to the frame.

The red wire comes from a box labelled "battery control center" fuses inside. Inside is the setup for power to the slides - fused and the control to interconnect the chassis battery.

The number of cables on the battery may not be a good way to determine if everything is disconnected. In my Sanible 5th wheel I only have one main positive cable connected to the battery but that cable goes to a positive bus bar and then the bus bar connects to the main fuse panel by another cable. So the other connections to the bus bar remain hot even when the disconnect is pulled. In my case only the main fuse panel is disconnected by the battery disconnect. I did add another battery bank and another battery selector/disconnect and that switch will disconnect everything.
