Michigan's got your back. I am familiar with the Fun Finders, and will keep a look out up here for you. If the local police are not very interested perhaps you might contact the state police, they may know more about such matters, if this was random or a growing pattern. Also, I would recommend contacting your Sect. of State's office and ask if someone would be able to reestablish ownership of a stolen rv, how would you prevent it, and if they have a list of stolen vehicle vin#'s to run before anyone other than your parents can lay claim to it.
Best of Luck, I hope they catch and prosecute the thieves.
