Yes, I had water there and on the other side of the bed on our maiden voyage. Camping World found that some piece that should have been in the slideout was missing from the factory. It was not found until the slideout motor failed and when they went to change it, the whole area was full of water. Ruined my mattress...which was replaced by Camping World. I wish I could be more specific about the location but that's all I know.
First, they thought it may be coming from the a/c. They checked that and tighten some screws. They told me that if the slideout motor hadn't failed, they would have never found it.
We just got back from our second trip...no leaks!!! I'm a happy camper now.
