Some think of the sealing and that IS important but I think of the batteries as one that catches lots of new users as it is not at all clear on what we need to do to keep from ruining the first set of coach batteries.
The coach battery disconnect, DOES NOT disconnect all the load on the coach batteries!
That means we can turn the switch off and think we are clear to store it without the batteries running down to damage them.
But the "funny" to that is there are safety items that come off the coach BEFORE the disconnect and are left powered! CO and propane detectors are a couple that are so safety oriented that they are left connected, so don't let that slip up on you, if you get into storing for a while!
I did a snip of this part to let you see what I mean and how it can catch us!

Winnebago marks wires along the side like this:
This is the list to "decode" the labels used on drawings or the wires and it tells " from" and "to" of that wire! Often we can tell the use of that wire, like if it comes from a fuse, ground, etc.
On the battery disconnect drawing, we get coach battery coming to the disconnect and a wire GJ taking off BEFORE the disconnect and going to a small buss for the safety items.
Most of the coach battery does go through the disconnect if it is closed and comes out on wire KKF to the circuit breakers! KKF gets cut off, GJ doesn't!
One to be aware of if you store the RV as it will run the battery down if not doing something to keep it up!
