just a quick update on the Ford in-between-rails hard folding cover available from factory (its FORD branded but REV makes it - thou pretty sure its a Bak-flip) . so far so good.. almost 2000 miles on my truck - hard cover been there since i picked it up. everything inside stays dry and clean. I have had 8 inches of snow on top, i clean my truck with a power washer and i live 3 miles up a dirt road.. Cover has performed ! so far so good.. see pics above.. any questions let me know.
