Those checklists are very good but the first thing we do when we get to our campsite is block the TM's wheels and level the box by dropping & adjusting the height of the four legs as necessary (we also have Andersen drive-on side-to-side levelers). Then we disconnect the TV and continue with the "opening" process, pretty much as indicated in the docs. I just thought it was unusual to raise the shells before leveling...??
