..Away back when (we were younger and the kids were still young);
We used a much less refined variant of what I still/currently use in the back of the Jeep TJ vehicles have changed over the years but when the STUFF pile gets too large for the vehicle its time to reduce stuff not normally to get a bigger vehicle or strap stuff to the outside, IMO;
The less fragile stuff was stored in the garage ready to load; tent (s for kids), awning/canopy, chairs, cots and air mattresses ground cloth and tarp etc.
The 10 to 40 liters worth of empty scepter cans/french wine tins are stored (clean , dry) in the basement, or pantry along with the canteens (empty, dry).
The usually empty, during storage ammo cans (some are stored inside of others) for dry foods are stored in the pantry.
The larger Apache (from Harbor Freight) case of cooking gear is currently kept in the spare bedroom; it never gets unpacked at home and gets restocked, if necessary, immediately on return from the trip... the priority is what you NEED not what you want.
The clean cooler is stored in the spare bedroom.
Along with the camping end tables and the small folding/collapsible table.
The remaining 2 medium Apache cases; one for miscellaneous stuff like coffee cups (they refuse to fit in the kitchen case) and tunes/ electrical gear fit in one case and the wash up gear (including the dog bowl-sink and kettle to heat wash water, fits in another... after arrival they are stored under a cot.
The clean port-a-pot gets stored in the spare bedroom with a spray bottle and roll of TP inside along with a full compliment of chemicals (restock immediately on return).
The tent battery gets stored on a battery tender in the basement.
Everyone gets a small duffel for clothing; if it gets soiled hit a laundromat.
There is normally extra room in the Jeep if I go alone; if another person comes along there is an additional cot, with kids air mattresses are sufficient, along with a sleeping bag and small clothing duffel each... kids in diapers are a special case.
My thoughts; stock up before leaving home and get the stuff you forgot at the last stop/town before you arrive.
Leave the area cleaner than it was when you got there.
Be a good neighbor.
Don't do, modify, tear up or leave any thing that would be out of place in the nicest front yard (hopefully your own) of your home neighborhood.
Enjoy!
