Congratulations Rick, The only things I would add to the list would be:

Get your computer all set up in the bus so you can communicate with POG before you leave Legendary.

Stock up the bus with some basic food and beverage etc., so you are not forced to make a pit stop when you don't really want to. Take a friend or two along for the pick up. It's more fun and just in case something goes wrong, misery likes company.

If you are not going to video the instructions as Deb suggests, get a digital recorder and do it that way.

Be sure the dump hose is on board and do a hands on use test
