Welcome to the campfire.
My suggestion is to get in as many short trips as possible and use all systems before embarking on the long cross country trip. In the middle of nowhere on Sunday evening is not the time to find out an unused system isn't functioning.
Also, go out to the Thor Owner Resource center and register your VIN. The download all of the documentation for your coach and have that with you while you travel.
Again, welcome and may your travels be safe.
