Hi Neil:

Yes, I have the link for that particular set up. That would require using
the onboard 13 gallon water, which is not something I was interested in
doing. The link I provided appears to be an "on demand" system, that is to
say as long as you have adequate water supply, (stream, lake, etc)  you
could have endless hot water on demand. That's a lot different than heating
up the onboard water. The key is the type of heat exchanger. There are
propane units available such as the one I have (Coleman) and I believe there
is another company that puts out something called the zodiac, which works on
a similar principle. The Coleman actually works quite well on a picnic table
with a 5 gallon jug, but it is kind of large and bulky and takes up precious
space. Anyway, as I said I'm intrigued by the challenge more than anything
else. In my own experience, there seems to be plenty of places available
along the way to get a hot shower for cheap, and the Coleman works great at
picnic side for dishes, etc.
