I don't think the "group" can help you without some more information from you. Has the leak or leaks been fixed ? What model motor home do you have ? Can you provide pics? What type of ceiling material do you have. Some stuff can be cleaned up/salvaged, while some other stuff would have to be replaced.
I just realized your post is titled after the leak, so I guess it's safe to assume that answers my first question, if the leak has been fixed.
