Hi: Ken C... Most of the fasteners around the joint seam just hold the metal base for the rubber rub strip. There are however places where they hold into the wood blocks glassed in to hold the interior cabinets in place. For that reason I think Escape
uses screws to do the job whether they just bite into the multi layers of fiberglass or into the wood blocks. I have yet to pull open that seam cover but am going to when "Our Escape
Hatch" is out of storage!!!
The top and bottom molds are glassed together and then left to dry before being unmolded. This vital step makes them align perfectly and allows the cabinettes to be made to a set of templates and installed all at once. There is a good set of pic's on escapetrailers.org. I'm sure Reace could explain better than I. Here's a pic of the storage area under the dinette bench. I think it shows one of the awning
