Sounds like you are getting comfortable with it. Congrats.
Something I did for mine is to make a check list when we get ready to depart. I found as I got comfortable, I forgot stuff. My list starts in the front of the rig, bedroom, in the closet and goes back. I start with making sure antenna booster off, dresser drawers closed, lights off, then that the closet drawers are locked in place. Then AC is off and so on as I go around the bedroom until I get to door and close and latch it. I then do this for every section of the rig until I get to the very back. Didn't use the list a couple of trips ago, found I forgot to put TV retaining straps on when I got home.
Sounds like you have a pretty good dealer too.
