I just got back from a 4 day backpack trip in Aravaipa Canyon,
Arizona and used my 2 burner stove [Expedition] for the first time. One of the legs
broke right next to the burner but the stove still worked and cooked many
meals and heated a lot of water. The stove seemed to peter out after about
1/2 of the bottle and did not put out the same amount of heat as it did
with a new bottle. Just thought you'd like to know about this.
We haven't had any problems with the Xpedition. Well, one, but that was our
fault. We spilled a lot of water from a cook pot onto one burner and it
wouldn't restart until it had a chance to dry out a day or two later. The
other burner continued to work just fine, so we didn't have to suffer
through cold food.
The more experienced members of our test crews have always preferred
multi-fuel (white gas) stoves to the cannister models. The more we work with
the stoves, more of th eField Test crew is moving that way as well. One of the
primary reasons, which you mentioned, is that as the canister drops below half full,
performance may decline--especially in colder weather. Also, as the
cartidges get less and less full, you can't tell exactly how much is left,
and you tend to take a full one on your next trip, just to be safe, leaving you with
lots of partially filled canisters.
With white gas (or other liquid fuel) stoves, you can top off your fuel
bottle before each trip. We use the MSR bottles which come in two sizes.
For most trips of three days or less witrh one or two people,the smaller bottle
has plenty of fuel and saves a few pounds.
For those who need the convenience, canister stoves are still the simplest
to operate, so they do have their advantages.
Thanks for your comments.
