By now i assume you made your maiden voyage.
Hopefully it all went smoothly.
My only advice would be to make sure everything operates as it should. Most things are covered in the PDI, but we have seen things work on the sales lot, but once in the real world, not so much.
Necessities are going to vary from individual to individual, what might be a requirement for me may not be to you, but some main items, wheel chocks or x-chocks, fresh water hose, sewer hose, leveling blocks, just to name a few.
Keep a list of things as you camp, what needs to be repaired or attended to, things you forgot, things that would make life easier, this way you will remember them for the next trip.
Most off all have FUN!!
