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.
It is true about a few posts stating such. Not a lot of examples but this subject is not one of the more prolific problems. Consider all the openings on a camper. Basement doors and such are not air tight and they are just one way for air to get inside the living area of campers. The heater is under the steps going to my bedroom. If I open the basement door I can see light the the opening between the steps. The joints between walls, ceilings, closets and such are not sealed.
