First, Congratulations on your new coach and welcome to the forum!!! I’m sure someone will chime in with the link to Ed’s manual which will be a great resource for you, it has everything you need to know about your coach.
You don’t have to put the switch in the store position, even when you do that there is still a lot of parasitic drain on the batteries, just leave it in use all the time. The batteries won’t charge if you’re plugged in and switch is in the store position.
Hope you have lots of FUN!!!

One day your life will flash before your eyes,
