I did what you have done in the way of preparation and was glad for it because my first big trip had no issues. One thing I learned to do is make a "Let's Roll" list which is a checklist of things to do before you leave an overnight stay. Awning closed, TV antenna down, vents closed (if you don't have covers), entry step raised, entry handles stowed, exterior compartments locked etc. After a while this evolved to other methods of reminders for the items I was most prone to forget - hair clip on the steering wheel if I raised the TV antenna.
Bon voyage!
