Exclamation Aquahot leaking under coach

I noticed that my Aquahot is leaking under the coach. Initial evaluation is that it is coolant. It is not diesel fuel based on the feel and smell. Today I will try to look underneath to see where it's coming out. I realize that will not mean much because it may be flowing from somewhere else to wherever it is coming out. I checked my overflow tank and it is empty I just filled it up from empty two ago I guess that should have been cause for alarm. Anyone have good ideas on where to start looking. If there are no simple ideas, this may be a big enough problem that I need to take it someplace rather than tear the whole thing apart myself. Full timers don't have the option of a nicely equipped garage and the flexibility of timing on this kind of thing.

So, what do you guys think?

Sometime the radiator cap is bad and the hose to the overflow cracks or comes loose. I refilled the radiator, but forgot to take fluid out of the overflow and when it got hot, the overflow tank spilled over.

you can tell diesel by the smell. If it doesn't stink of diesel, its boiler fluid. The Aqua hot doesn't use standard anti-freeze, it uses a food safe type (called GRAS or Generally Recognized as Safe) at a concentration that will convey heat pretty well. If you are leaking boiler fluid. (The fluid expands as it heats), Check your radiator cap which allows accumulation of a few pounds pressure in the tank and that slight pressure probably found a leak that isn't there w/out the pressure.
