I have decades of experience in all conditions with the similar Coleman liquid gas stove. I have used the propane model too and it is very good. The thing is though, in an emergency situation, you can't suck propane out of your truck or lawnmower gas tank.

It is solidly built and has a heavy grate, two burners, and a large windscreen. It burns readily available Coleman fuel or regular gasoline. The heat is fully controllable for each of the two burners, and you can use your regular cookware on it. It is virtually bullet-proof, folds up to briefcase size, and tucks away. Should any part ever wear out, replacement parts are available and cheap.

There is always the regular propane gas barbeque grill with side burner and standard tank, although I worry about the availability of refill propane in a large scale emergency. On nice summer days, I already have to stand in line at the gas station waiting for a propane fill, and paying through the nose to boot. An option if you live in an area where there is natural gas service, you can get a gas conversion kit for your grill, and have a gas quick-connect outlet installed on the back of your house. If you live in a rural area and have a big propane tank, you can have a gas outlet installed too. I would have a gas company technician do these installations for safety reasons.

Powered by 2.5 pints of fuel - 2 hour burn time on high, 7.5 hours on low

14,000-BTU total cooking power (7,500 BTU on main burner and 6,500 on auxiliary burner)

At $60, the Coleman multi fuel suitcase stove is a great emergency home and truck camping option.
