The only thing I worry about with a dual fuel though is leakage and storage. Granted I could use propane exclusively with it until I find myself in a pinch, so it's a nice back up. Although I've read that the liquid fuel lasts far longer.
For those of you with a dual fuel, have you found any issues with venting, fumes, or leakage during transporting or storage?
Cool story: Like most adults, my Mom eventually made the phone call that begins with "Come get the rest of your childhood crap out of my garage." I dutifully went over and cleaned out a bunch of crap, but also found a cardboard box with all my old Boy Scout backpacking gear in it, including my late-'80s or early '90's MSR Whisperlite (white/coleman gas) stove, along with 3 fuel bottles, two of which had been stored full. After more than 20 years in the garage, the fuel was still the right viscosity so I thought "what the heck". I blew the spiderwebs out and tried to light the stove. Pumped up fine, primed and lit just fine.
After all that time, the only noticeable degradation was that the O-ring seals on the bottle caps and the pump were pretty cracked (but still holding fuel). I put new rings on everything and went through the stove with a rebuild kit and the stove still works like new.
Similarly, I've pulled coleman stoves out of their cardboard boxes from garages, etc. and they all seem to do just fine. The only leaker I've ever come across was an early 1970's model at a yard sale that had been stored such that the leather gasket/cup thingy in the pump had dried out. Replaced, and that stove still runs 100% also.
The only reason I don't use white gas more often is that I'm a zombie in the morning and prefer the pump-less ease of a butane burner to get coffee going, and I've had issues with hot-re-lights on coleman stoves (they don't always re-ignite cleanly after being off for ~20 minutes) - required a lot of fiddling.
