I see lots of posts about specific elements of a camp kitchen, A picture is worth a 1K words. Post pictures of your camp kitchen. I'm sure their are lots of great ideas. Please comment on your favorite camp kitchen feature.
Our style of travel is basically expedition style, where we are camping somewhere different every night and typically wild/dispersed camping so we setup off the tailgate of my Cruiser. It's evolved over time.
Some features that really help are having water with a downspout off the swingout for washing and drinking water/filling. Also, the fridge (of course!), warm, bright lighting on the hatch, 5#propane tank, having a quick table to pull out. Trasheroo makes it super easy with all garbage. Most recently, I built some simple drawers for all our food and camp gear cuz I was tired of stacking, lifting, opening, closing,packing and digging thru my containers. The drawers made a huge difference and maximized storage. Started off basic. Swingout made everything quicker and more convenient. (Water, fuel, propane, trash) Drawers made of 1/2" Russian birch with teflon slides. Just need to rebuild the fridge slide with the fridge turned handle facing out.
