Aside from what was mentioned above you will need a good sense of humor. Things will break, you think you will plan for everything, use 10% of that and forget something you need on almost every trip. I probably have 6 can openers because I forget one on every trip and keep buying new ones. And I have been RV'ing for decades. You have to watch your weight on carrying things you won't need just to have it. A few trips and you'll sort out what you need. Stick to the basics for now and learn as you go. But without a sense of humor when you realize you forgot something, or something breaks, then the fun is lost. Most fellow campers are helpful and you can usually get by with intuition, help from a fellow camper or a trip to the store.
