No problems like that so far, thank goodness. We've gotten 5" of rain here in the lasting two weeks and I've been in and out if the RV getting ready to leave out next Saturday morning, so if it was there, I should have seen it. Only thing I've found was in the front passenger compartment this afternoon. Looks like maybet He top door seal is not up against the door with enough pressure, so I had some water in there. Is your unit sitting level? If not, there's a chance the condensate pan could be holding water instead if channeling it to the drain tube. Also, the leak could be elsewhere and just following the air ducts to where you see it.
