The camper will be nice to have but expect the environment to be extremely harsh on it. Bring the generator and run it if you want. You may find that you don't need it at night depending on when you come. You may also find that the AC can't keep up in the daytime. If you plan to run down the beach, then a 4x4 is a must pulling the camper. I know they ran it without one back in the day, but I wouldn't even think about going much past the 10 without 4x4. Talcom powder is your friend. Lots of stuff to consider for a few nights on PINS. October can be hot as heck and then cold as heck. Under Armor is also your friend. Precook and freeze your food. This adds to the ice content of your cooler. Bring an ice cooler that you don't open. Bring a food cooler that you rarely do. And bring a day cooler for your drinks. Realize that on PINS, you are, at 15 to 20 mph, a ways from medical care. Also, be very considerate of others on the beach. It promotes like actions. They will not always be that way to you but most will be.
