Hey Oliver here are a few pics I just took this afternoon of my water bay mod. This first pic shows the little panel placed back where it was originally.

Here is what it looks like now. I also nibbled off a bit of the edge closest to the door trying to fit a 3 prong plug head through the opening (to no avail I might add).

As far as I can tell this is the only opening between the heated furnace bay and the tank bay. Doesn't seem like much does it?
Here is a pic of my little ceramic heater in the bay.


Here are several pics just taken late this afternoon. One of my suction cup assemblies has fallen completely off the side of the coach and is just hanging. The suction cups suck in these cold temps but not in a good way.


Look at the icicles hanging off the lower portion of the AquaHot Genturi exhaust.
