Hi Helsa,
If I was camped overnight, I would put the kitchen away, mainly because I don't have the awning up and as it is a timber kitchen, I am concerned about dew. If it is a longer camp, with the awning up, I tend to leave the kitchen set up as well.
As I have the Drifta pullout and return, I mostly have all my kitchen things in it already, including my food stuffs that are non perishable. If I can't fit all of my food in the kitchen, I use a couple of plastic bins.
Ages ago...it seems! Kit_e posted up an awesome pic of her spice array. She uses the tiny zip lock bags to store spices and herbs, which is a great idea! I have found the little round storage containers from Woolies are also great, though they probably take up more room than the bags. You can buy them in two sizes.
My friends with a Lifestyle CT and a tailgate kitchen, store their food in the plastic bins with lids and put their kitchen equipment in under the bench. They have found that they need to be a little more organized though and make sure that they put like food stuffs together. Either that or put a list on the lid of food that is in that bin, so that they aren't searching through everything for the one item they need.
