Welcome to the forum Black,
As GG said, Pack as if your tenting, live like your in luxury!! I too went through the Tent and then camper "evolution" (As I call it) there will always be something that comes on the market to make your life a little easier, however, if you cover the basics, (no doubt after 30 yrs of tenting you will have that nailed!!) you will be on your way to an even better experience.
My transition I found storage was my biggest review, rather than have lots of things you need all over the place, I could box it all up and keep things tidy and in their place with a camper. Your storage area allows you to keep cooking utensils, food, electrical, clothes all separate and easy to get too. Plastic tubs are the way to go I feel as they allow you to keep things portable, accessible, water and dust free, clear ones allow you to know exactly what you have in what box (the simple stuff I know....but usefull)
Anyways, good luck, travel safe
