When Bob says “disconnect” I believe he is suggesting you remove the large negative wires from the battery terminals.
Simply putting your Use/Store switch into Store will not eliminate all of the parasitic draw on your batteries.
A 15A outlet is fine for plugging in your Airstream. You won’t be able to run the AC. Microwave and electric water heater will be iffy. Everything else will work. With Use/Store in Use, batteries will charge.
The older Airstreams, mine included, had a fairly dumb converter that will boil your batteries and ruin them if left charging 24/7. The newer ones are supposed to have smart converters that will not damage your batteries.
A timer at the outlet set to come ‘on’ for one hour a day will keep your batteries charged without damaging them. If you’re going to be using the Airstream, delete the timer.
You will need an adapter to plug your 50 amp cord into the wall. Any camper store will have an assortment. Get a 50A-30A adapter while you’re at it so you can plug in to a 30A pedestal at a campground.
