Water pooled under furnace

[reidfo]

I just had my first night in my new to me RV and it went well, but I have a couple of issues. I'll post the other in electrical, but I had water pooled (a few paper towels worth) underneath the furnace this morning. Saw some last night too which I cleaned up, and there was more this morning, so I'm suspecting condenstation.

Here's the background. I've seen other threads suggesting water intrusion from wind and rain through the exhaust. No rain in the last week, and no wind last night. It was cold, so the furnace kicked on a few times overnight and yesterday.

We did have a hard freeze here in humid Texas the night before I left. I had a space heater inside for a couple of days prior to leaving, faucets open, tanks drained. I haven't found any evidence of leaky pipes now that I'm hooked up on city water. Looked under the sink and in drawers and found it dry.

Any suggestions on where to look?

Hello. The outer cover of my furnace did not have thermal insulation and there was condensation on that metal sheet.
If on the outside of the motorhome that cover is warmer than the rest of the surface, it means that you don't have thermal insulation on it either.

Thanks. I'll check tonight to see if that's the case. I've run water in both sides of the sink today and haven't seen any water, so I'm pretty sure it's the furnace and not the sink.
