Damn again Jim!
That's the same page I was reading when I decided to post the temperatures hahaha.
lol. Told ya. Great minds think alike.
the zenstoves website is also a great source of info on canister stoves.
Yes, it is, isn't it?
Now, something that is based on personal experience rather than a website: one real drawback to simple canister stoves is wind. Since there is no wind screen, they are susceptible to significant wind. They can blow out, but what occurs more commonly is that you lose a lot of efficiency and wind up using a lot more fuel to do a given amount of heating. Yes, I am aware that in this case were talking about a stove to be stored in someone's car kit, but if one were to go camping/backpacking and significant inclement wx were predicted, a canister stove might not be your best choice. A white gas stove which has no problem with a wind screen might be a better choice, although wind screen or no it too will be affected. There are some really pricey newfangled stoves out there (Jet Boil, MSR Reactor, etc.) that handle wind well if that's a feature that you need for what you like to do. Just something else to factor into the equation.
