I've been building a large vehicle based camp kitchen since the end of last year, lot of same themes, Zarges, Norgie etc....
It's obviously a big kitchen setup, but it's all easy to pack and move. Bit too big for a car, but fine in the back of a landy or a good sized 4x4. It can be used under a tarp or inside a large-ish tent or tipi. It can hold enough food to feed 2 people for a month and the 6kg gas bottle will power the twin 10,000 BTU burners for an hour a day for 28 days.
If there is a weak point, it's the lifesaver water bottle, great bottle but too small for this kind of setup. It'll only clean about 500mls of water at a time, which is fine for backpacking, but it's a mismatch for the rest of this kitchen kit. What I would like is to replace it with a 20 litre lifesaver jerry can, but they have only just come onto the market and are hellishly expensive. Maybe I'll pony up for one when the price comes down a bit or they start appearing on ebay or on the army surplus market.
