I have things I use for normal recreation that double as my "normal" and "extended" plan for things like cooking, boiling water. I have stoves and pot sets that include solo and multi-person for backpacking or canoe/car camping. Depending on what I'm doing, if Mrs EITS is with me, etc...that determines what I take/use.
Coleman 425. I love these. I pair this up with a cast iron frying pan, a stainless steel coffee percolator, and a small pot and that will do pretty much everything I need it to do for cooking.
MSR WhisperLite International for colder temps, and a
MSR Pocket Rocket for a canister stove (love how fast/easy this is). I pair those up with either the
Weekend HE (the heat exchanger...very quick boil time...and I use a windscreen as well) or the
Pinnacle Dualist II.
I considered multi-fuel versions like the
Coleman Guide 424 and the
MSR WhisperLite Universal, but the cost and uncertainty (I've never known anyone who actually used one) made me go with the standard ones. If naptha supply becomes a problem, gas etc might be too. I do wish I would have at least went with one multi-fuel...
But, I do have a backup for 'no fuel' times;
Kelly Kettle. Right now I've only got the aluminum Trekker kit complete (hobo stove, etc) but I have the intention to get the BaseCamp kit in stainless steel.
I also have a nice size cast iron Dutch Oven.
Last buy not least, I opted for a portable propane BBQ as well; a
Napoleon TravelQ™ 2225. With the adapter hose, I can use standard propane tanks (have 2 x 20lbs...that is LOTS with this BBQ). Also have the
stand made for it which is a 'must' for me for home/car camping use.
Between all that, they are all double-function in my mind; home use, car camping, canoe camping and backpacking, whether strictly 'recreational' or because something went sideways and I "need" them.
My wife thinks I just like to 'buy stuff'...I just like having 'options' and the ability to be mobile, for both recreation and 'SHTF potential'.
