I think it's a pretty nice set up, has the cooking system built right in with the canteen, they don't list what it weighs and depending on if your packing in the weight might be a factor, I have seen something like this before, one of the guys at Denton Hill had something very similar. As far as water goes, if you don't want to carry your water get a Sawyer water filter, I hear they are pretty good and I'll be picking up mine pretty soon for this coming camping season.
Thanks for the info.
