Hi Steve
I like that unit. That is what I wanted to do a few years ago but
nothing was out there. I settled on
http://www.amazon.com/Hot-Water-Demand-Port-Htr/dp/B0000AE6XA
You use the little green LP bottles or we have the larger LP tank and
adaptor. You can hook to a garden hose or 5 Gal camp storage tank. I
wanted it to be self contained in the Vanagon. I'm really interested
in what you make work. Venting it to the outdoors and having hot
water on demand is the best. My wife loves the coleman thing we have.
Easy to use and you can move it anywhere on the campsite. Quick for
Hot cocoa and Tea. Nothing beats washing the dishes with warm water.
I've been looking for a way to move it all inside the vanagon. I
removed the Fridge since we never use it so I have capped lines
behind the wall to tap into the unit. There are already on board
water tanks on the vanagon as well so it would be nice to use them.
