Emily,

        I toured the factory in Iowa where Winnebago does the conversion on the
van for VW last year.  They have a really large service department
taking care of owners' vehicles, and appear offer service on all the
products they have made.  You should contact Winnebago directly and ask
them for advice in how to deal with this problem.

        Also, if you happen to drive through Iowa, just stop by Forest City
(central north Iowa) and take the tour of the place, you'll find it
interesting.

        You can find them on the web easily enough, I'm sure.
