Why do Class C's always leak in the front upper bunk area?

Until the industry gets away form using goop to keep water out leaks will continue to happen.

My dad has a 1998 Chinook Concourse. The body is a one piece fiberglass tub. No seams, no caulk, no leaks. Of course, when it was new it cost as much as a 4 bedroom house in the suburbs, but it won't leak. You are absolutely right, ScottG... No goop, no leaks.
