We have an 87 with a westfalia poptop roof 3/4 with the luggage bit at the front.
Question being, where does the rain water go?
The moulding at the front is recessed to take luggage and has holes in it to drain any rain water so it doesn't get filled up. However it sits on the roof and has a rubber seal were it sits on the paintwork of the roof.
Is this void under the pop top filling with water ?

How does it get out or is this damp area going to eventually rust through the roof panel ?

Your help and advice is really appreciated.
As a footnote, spent a fantastic day in red bussy (as the family call her) on the common today, and as I looked out at our children playing as I cooked some sausages with beer in hand, I couldn't have been happier. Everyone should have a camper at some point in there lives.
