Wow, what a lot of variation! Isn't that great...? Obviously most of us put a lot of thought into food and prep vs freeze dried paks and or protein bars (blah).
My wife and I typically hit the road for 3-5 nights at a shot before swinging by a grocery store/gas up, etc. In doing that we've (at least for now - who knows what future years will bring) ditched the two burner and have opted for 3 single-burner rigs. I use the screw on single burners that mate to the green one pound cylinders and we keep a snowpeak burner plus a jet boil pot for quick water heating (coffee, afternoon tea, etc.).
Rationale? We usually end up cooking in unison with one of us working on the veggies/side/bread and the other working on the Main dish. We found a two burner stove was too crowded and we got in each other's way (I should add we've been married for 30+ years so getting in each others way has been an adventure in itself!! LOL) This allows us to "cook where you want" either on the tailgate of the pickup, on the collapsible table, or sitting by the fire pit.
Also if we damage something or run out of fuel, a quick swing past any hardware store, Walmart, Target... allows us to restock our kit and keep in truckin.
