I thought it might have been, just wasn't sure what to search for lol. Will see how I go
Found this from something I typed up in another post. Can use it as starting point, perhaps. Cheers Pace.
Corelle are what we use. Our van is like as if its home, fully loaded ready to go at the drop of hat. When we had the Swan we transferred all to Expanda. Plastic cups are the go like Mick suggests. Don't forget a small heater, toaster, kettle, all the pots/ pans, cutlery for all the family (plus the odd blow in, now you've got the room to house them, because trust they will come!!!), pillows/ bedding/ sleeping bags (yes fitted sheets can stay on the mattress as you pack up), mattress protectors for those little accidents that can happen, batteries, torches, spare keys (both car and van, because accidents will happen and keep spares in car for van and for van in car, has happened to us!!!), tape fittings to match wherever you stay for water supply connections, spare o-ring for van nylex fitting, flynet repair kit.
As for toolbox, I'm sure there is a thread detailing things of essential to carry, though each to there own. Just look around, inside and under the van and have a think what could get caught on things that might need temp repair to get you by. Some will suggest a cordless drill and duct tape is the go too, yes i carry them. My thinking is that if you carry it you wont use it, has worked so far for us.
Are you mechanically minded or a "bush mechanic" (no offence intended any one), this too will warrant what you carry. If you watch 4WD shows, bush mechanics are everywhere and the things that get them by is quite clever.
