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. Troy
