Don't have a pic, and we're on a side trip right now away from our rig. But there was a small gap about 2" wide below the convenience center and between the frame and the J-wrap. It was enclosed below but there were holes for the two low point drain lines that allowed cold air to blow up right on the plumbing. This was just the thin aluminum outer panel that wraps around the bottom of the body. I wedged the piece of foam between the frame and the back lower portion of the convenience panel and that sealed it up. A simple and cheap fix and I suppose one the dealer would never be expected to catch in their inspection. I would guess that they would normally use spray foam at the factory to seal the holes the drain lines run through like they do in other areas where pipes and wires penetrate the coroplast. Curious though to know if anyone else has had a similar issue.
Even if your not exposed to freezing conditions it would be a place for mice to get in.
