Bed cover
My cover arrived on time. FEDEX had mishandled the shipping container and should have used a 2-wheel dolly to move but they grabbed the shipping strips instead which caused the box to be badly damaged. The instructions were torn as a result. I thought the top was supposed to be a unique fit, but instead it’s a universal fit for several trucks. However, it does fit securely and holds up to highway speeds. It is also fairly easy to fold up and secure.

Trifold tonneau
Excellent product and the right size this time. Also ordered fender flares for this truck that didn't fit quite right. But for every problem there is a solution. Didn't fit flush to the truck so I took a heat gun to them to make them fit properly.

Three panel bed cover
The cover was delivered quickly and I put it together as soon as I got it off the FedEx truck. It took about 30 minutes to install it. Looks great and works perfectly with my 2011 f150. I highly recommend it

Great hard cover
Easy to install, took only 15 minutes. Low profile and it upgraded the look of the truck. Sturdy, strong and a great fit and finish. I live in Tampa, FL and it monsoons every afternoon. Went to check after driving in the rain and the bed was dry. Very satisfied with this product!
