Damp Floor in Slide Out

[annmarie]

Hello,
I have damp carpet in the front corner of my slideout. I checked the rear corner and it appears dry. The windows don't appear to be leaking and the walls feel dry as well. Any thoughts on where this is coming from?

Before we brought the trailer home, we noticed the bottom slide seal was completely busted and not functioning correctly. The dealer fixed it (over the course of several days) and then we took it home. Could this be related?

We're just about to store it for the winter and I have concerns (obviously) about how it will hold up stored outside over the course of a Minnesota winter. Will a closed slide out have the same issues?

Thanks in advance!
