Got the Bakflip MX4 from BAK Industries and had it installed in around an hour. Also used the clamps that were recommended on this thread from MM1 (thanks Matt!) and they worked like a treat with no issues. Then I got inside my own head and read the instructions that came with the MX4 that included specific instructions for the CarbonPro so I wound up drilling through the plastic caps on the bed as I figured I would never remove the cover anyway since it allows full access to the bed.
Love this cover and the whole kit. It isn't waterproof yet... But I have plans on that. After a downpour at the shore it had a couple of leaks but honestly kept out probably 97% of the water that was coming down and we are talking buckets here.
Geat design, great system and great look that was designed for this truck from the outset. One of the posts to hold the cover up while traveling was damaged in transit but BAK shipped a new one next day so no issues there. Super happy with this purchase from this company. Now onto the next unnecessary upgrade...
