One comment about your Arrival checklist.
Plug in surge protector THEN shore power cable is too far down on the list.
I have pulled in to a site, only to find that the power box is completely bad.
I'd rather find that out before parked, unhitched, and leveled both directions.
only to have to redo all of that on another site.
I will make sure I am level laterally, but before I do anything, I plug in, and make sure my microwave light is on. It only works when on shore power, so I know the box is good. Then I proceed with everything else.
