Glad to have you with us here in the forum.
After a few days camping you'll know what you need and what you don't. On the safety side a good surge protector, water pressure regulator and hefty fire extinguishers. It's always a good idea to have something to keep you entertained if you get bad weather and wind up holed up in your TT.
