Chairs, adult beverages and a bonfire. Have fun with your new camper, sounds like you got the basics covered.
You may need something to park one side or the other on to level it from side to side. A garbage can, a broom, and then all the things you bring tent camping. Food clothing, pots, pans, ect. Head to a resale shop to purchase cheep stuff you can keep in the camper. It makes life much easier.
