I have to say that it is a strange place to see water seepage. Dalemac no worries about your comment....I've seen people with their slides out as well just not in our Northern winters.

The water spotting was too wet to be condensation, especially since the rest of the trailer was dry as a bone.
Chuck you are right we don't have a topper installed on our slide....not sure about the ice damming effect....something to think about.
We didn't notice it when we first opened up our trailer after it had been in storage for the winter but then it's pretty much hidden behind the trim of the slide. I'll have to see if I can post the pic that I sent the dealer. We had a downpour after we opened up the slide and we are wondering if perhaps the top seal didn't seat itself properly after being stored in the cold. Some water could have gotten trapped inside when we brought it the slide...a long shot but a possibility. Our cruiser is just under one year old and we've not had this issue before now.
I haven't had any responses that anyone else has experienced this problem. Thankfully it's not done any real damage other than some water marks and that's mostly hidden behind the slide trim. We do want to make sure it doesn't happen again though.
