We always used a flat sheet for camping as a kid. Same thingy without the grill. We put a A3 size can on the could for a Billy, a big Apple tin or similar with a wire handle. Done some primitive camping with my brother back when people could be trusted and kids could be trusted with matches.
Tried various things to make my life easier when our kids were young. Quick tents, swags, camper trailer bigger Esky bought and sold em all as I tried some fangled idea.
Always reminding my wife how much I liked camping when I took my ute, my dog my Hotplate/Flatsheet and an Esky..
She wins, we have a caravan, still tight still on a budget. But it's comfortable.
Ice! Some eskys or cooler boxes last well. Like the thick wall poly types or fibreglass.
Techni ice is a sheet of pillows containing a product that hydrates in water and lasts longer when frozen.
Engel fridge is great, about $1200 for a 40litre and rotating gear you will manage well.

Also look for the little camp cookers that use a butane canister.
About $15 at Kmart or Bunnings.
$3 per canister, lasts maybe 90 minutes or a lot of coffee's.
Keep it simple,
