After realizing I'm going to spend thousands of nights camping and traveling I focused on the two main items. Number one is sleeping. The better and faster I sleep the more productive I am. Different topic yes but the second major task is eating. I bought a 4x4 van and set up a real sleep surface and real kitchen. Sink, fridge and stove. The partner stove was logical. Spend the money, have it for life, throw it in a creek to wash it, don't care if it falls off a roof rack and never burn your food. No brainier. Buy one but it's not perfect because you have to set it up. That means finding a space, setting it up and fooling with the gas and hose. Somtimes my rig is full of other sports gear and I just want a quick meal or a cup of joe without "cooking" and stopping for an hour. For that I keep a backpack stove. Sets up in seconds and it will heat or cook anything a single burner can cook. It's 30 seconds from digging it out until cooking. If I could only have one stove this would do it all.

These two are the best of the best stoves. Use them both if your going to be on the move.
