I'm new to the forum. I have an 09 with a hardtop and want to get a deck cover. I'm trying to figure out what hardware if any I would need to instal this. I'm looking at the Bestop Duster Deck Cover ($125) and the Pavement Ends Tonno cover ($65). Does anyone know why the Bestop costs so much more? Does it matter that I have a factory hardtop?
