Be relaxed

if you forget something when camping improvise

What others have suggested are fine for basic camping..

Chairs and comfy ones are always good.
If you want to avoid running into town for food all the time.. Freeze the meat before you go and pack it well with ice. It should last a good few days slowly defrosting

We just used a fridge for the first time while camping and we even cryovaced (sp) our meat. Fridge was great but took up heaps of room in the car. We even had to take one of the seats out..

Most of all have fun!!!
