RealTruck UnderCover ArmorFlex Hard Folding Truck Bed Tonneau Cover | AX22020 | Fits 2015-2020 Ford F-150 6'7" Bed (78.9") | Durable Weatherproof Protection for Cargo & Tools

The product is beautiful, fit perfectly!I did the installation myself and mounting the rails was a little more difficult that the installation videos on youtube made it look, but still very manageable.The sections are easy to fold up from either side of the truck bed by just one person. There are to expandable compression rods (one on each side) to lock the folded sections up and open if you need more access to the bed for taller items.The cargo area is completely weather tight but it is not dust proof! This is NOT the fault of the product, just a warning to others. I was driving on some dry, dusty gravels roads and the vacuum created under the tailgate drew a ton of dust up into the cargo area covering everything with dust. There are also to small drain plugs that are designed to drain water from the bottom of the truck bed but not let water in from the underside and this might have also contributed to the vacuum and dust accumulation. I made a sandbag 'snake' to lay across where the bed the tailgate meets to cut down on the dust being drawn inside the cargo area.I've had this on my truck now for 3 or 4 years and it is holding up perfectly.
