Dose anyone know what the slide toppers look like and who they are made by if you order them on a New 2014 Rushmore Washington model? Want to know if they are like the Elite Dometic models that have a hard protective shell when closed, over the fabric. Do they match the coach and the other two main awnings? They are in black on the hardware and the under roll of fabric or maybe they are vinly is black also? They are optional but there is no information on them. Do you have any pictures of them open & closed? Do they really help with the heat beating down on the slides?
