Ikea's Bekam shelves. Keep items in a big basket to secure on travel days. Put on these shelves for easy access on camping days. Small items in small containers like on the bottom shelf might ride ok, but I'm not loving the glass.
This is a website with every kind of container you could want... These would be great for spice containers and they are just .75 cents each... I think I will get a big nice cookie sheet and decorate it... the add magnets to the bottom of these containers and make my own spice rack.
