I took the A/C unit apart this morning, found the rust hole where the water was pouring into the coach, cleaned the rust out of the hole, and put a layer of fiberglass mat in the hole, with resin poured on top of it. While I was at it, I also fixed the soft spots on the floor with some fiberglass mat and resin, now that I have the leak stopped.
I also patched the hole where the water heater hole was, and installed the replacement water heater. Now all I have to do is plumb it, and hook up LP to it.
I checked the stove, and oven, they both work as intended, with no leaks, so one less thing to repair/replace. Less work is good.
