Congrats!
You already covered the most important part - signed up for this forum :-)
The other posts covered most of your technical equipment. Here are some suggestions for the creature comforts:
- an outdoor rug for under the awning. Keeps a lot of the dirt out of the trailer

- Rubbermaid (or similar bin) for shoes. Keep it right outside the door. Slippers only in the camper
- If you spend a lot of time outside around the camper, (especially if you have kids) an outside trash bag holder with a lid. Bring it in when you’re not around/at night.

- A notebook for trip notes that stays in the camper. Phones are great, but you hopefully won’t always have service.
- For the first few trips, and the first trip every season, it’s nice to have a printed checklist of what you need to do to hook up, and unhook your trailer. It’s not difficult, but my memory gets fuzzy after a few months of not camping.
