I have seen several posts on this and other forums describing what billmac above this post stated. RV's are not sealed very well and considering slides, openings around the hitch and other areas I am not surprised that this would happen.
If that were true, then there would be lots of examples, but I've actually only seen a very few. I think the roofs are sealed pretty well.
