Solid cover, but not waterproof!
Fast Shipping, packaged nicely. Mine came with emblem stuck between gasket. Extang quickly sent me a replacement gasket and emblem. Installed easy on my 2013 F-150. Follow instructions!! First rain storm it leaked front hinge and rear cab. It also seems to small for bed, should be wider. Cab corners don't line up with tailgate. I have to lift cover after closing tailgate to keep gasket from pinching. It is what it says... one solid cover, but not waterproof. Should be cheaper!!
So far, so good!
Overall, very easy to install and operate. I read the directions for 30 minutes, and then the actual installation took about 30 minutes after that. It looks great, and it has improved my fuel mileage by about 1.5 miles per gallon. I've only had it on my truck for about 2 weeks, so I haven't had a lot of time to see if any problems develop.
