I highly recommend "camping" in the driveway for a couple of nights with a yellow pad and pen. Write down what you forgot and a different list for what you didn't use, but that list will change as you start camping someplace other than your driveway. Make that first trip close to home. Even after you start to take longer trips, keep that yellow pad handy.
Welcome to the lifestyle and the forum. The only stupid question is the one you don't ask. It was new to all of us at one time.
