Roof inspections are so important. The roof is the only thing keeping your RV from getting water logged. It is very expensive to repair water damage and it could be so sever by the time you notice it inside that the repair will exceed the cost of the RV itself.
On a side note, I noticed some campers this past weekend with a fire so large that the flames appeared to be 6 feet high. I think that is a bit dangerous considering it was between 2 RV sites that are only about 25 feet apart. Keep the fires under control as to not damage yours or anothers RV.
