Even though this thread is older it pertains to a problem on our 19. I hit a bird with the Highlander going about 65 mph. It went over the top of the TV and hit the trim band about dead center and the metal trim popped away from the body of the camper about an inch. When I pinched the black vinyl trim and lifted it from the channel the head of the last pop rivet fell out. It had snapped off on impact it seems. I think it would be best to drill a new hole in the molding rather than trying to drill the pop rivet shaft out. I can determine the hole diameter needed and the head size on the rivet. However I would appreciate input on the grip range on the rivet. Has anyone had experience replacing these rivets and what grip range was used ?
