This cover fits beautifully and looks great, and Auto Accessories Garage was a great outfit to deal with. I had ordered other items as well and they were responsive in dealing with my questions and concerns.
The only reason I did not give a rating of 5 for the cover is that the tonneau rails I received were of the wrong configuration for my 2015 Ford F350. The rubber shims glued to the rails were for a truck with slanted box bed rails whereas mine were square. I called and emailed Auto Accessories with suggested remedies and they arranged with BakFlip to send me additional rubber shims, which I received 2 weeks later. That allowed me to properly match the tonneau cover rails to my truck. Because I needed to use the cover immediately, I manufactured temporary shims to permit temporary installation of the cover until factory shims arrived. This added over 1 hour to my installation time. Also, one part of the installation instructions was not totally correct for my vehicle, which also added to the installation time. The issue with the rail shims could have been avoided if BakFlip had not pre-glued the shims to the rails (which they do only for Ford trucks), but included them separately to use or not depending on the truck bed rail configuration.
