To answer your question you need to tell a little more about what you want to do, and how. How many travelling? Kids? Want wild remote areas, or resort style campgrounds with tennis courts and swimming pools?
To figure out what you need, try staying in your camper in your driveway to learn what you and your family prefer. Keep list of all the things you run back in the house for, and then decide whether to always transfer stuff or buy new for either home or camper.
A weekend or two in the driveway to learn how to make everything fit and work will make your first short trip to a campground go a little smoother.
