Don't worry, no matter how well you prepare a list of essentials, you will forget something and take a bunch of stuff you didn't NEED.
The only check list you need is, "wife check, grandkids check, dogs check, camper hooked up and ready to go, check." GO check, have fun check, got home safe check.
Go camping add to/amend list while camping. When you get home take out all the stuff you thought you would need, but didn't use and leave it home next trip.
Seems every trip we prepare for one of us will say, "why do we need this, we have never used it." Amazing how many it nooks and crannies you can put stuff and then forget you have it.
Go, enjoy and learn as you go what you really need to be comfortable.
