I'm unsure as to which kind of roof is on my RV. I have a '97 HR Endeavor built on a Ford chassis. The roof feels like fiberglass, but I'm confused by what appear to be taped over rivets running down the center. Weren't these supposed to be one piece fiberglass roofs? I've looked through the owner's manual, but it's not providing information on what type of roof is on the motorhome. If there are rivets, doesn't that mean the roof is aluminum?
Thanks for any illumination you can bring!
