Very nice! Now, continue the set up in "Camp Driveway" and spend a night or two in it before taking off across country. I had my first one a week before going off to Yellowstone for a week of dry camping - I would NOT recommend that.
This will help you figure out what's missing, but you'll only get so close.
Unless you're going for a site with full hookups, you'll need to craft your own grey water tank.
