Thank for the response Ron that's definitely half of what I'm looking for.  That's the pull cable half.  I would also need the "valve" half that shuts off the dryer vent.  Any ideas on that part?  I'm unclear if this is part of the vent thru the side of the coach or if it's something inline inside the coach.

QCJ, I certainly haven't ever noticed this on any other coach I've looked at.   Let's hope it's not too expensive.
