Rugged Liner E-Series Soft Folding Tonneau Cover for 2015-2022 Ford F-150 6'7" Bed (78.9") | Model E3-F6515 | Waterproof Truck Bed Cover for Hauling & Outdoor Adventures

DidGreat buy workers GreatEasy installation. Fasteners do loosen with vibration. Recommend lock washer and nut to hold secure. Great otherwise.Easy install, nice value for the money; however, a little noisy while driving.After rain I found water in the bed of my truck. Contacted the company regarding this...and the pretty loud squeaking coming from it when driving. After providing them several pictures of where it leaks and the visible gap at the front left corner where the water intrusion came from (at their request), it was determined by them via pictures that 1) the front seal was not positioned correctly and that 2) the end caps on my F150 truck bed are the problem.My response: 1) I never submitted a picture of the seal position and it IS, in fact, correct. 2) My end caps weren't a problem for the last tonneau cover I had for more than 5 years. It never leaked.Suggest you consider an alternative brand.I purchased the E series soft cover for my 2018 F150 with a 6'7" bed.Construction quality is good.The problem is that it's just not quite long enough for the front weatherstrip and rear weatherstrip to touch the tailgate and header at the same time. When I move it back enough to touch the tailgate, I can see daylight across the whole front. It needs to be an inch or so longer.It was super easy to install, from the time it came in the mail open the box and putting it on took about 10 minutes.The gasketing is weak on the frame. The front piece, near the cab doesn't seal over the bed molding well at all. When driving air gets under the top and it flaps a lot while driving. Make sure you have the dust gasket installed properly, but I am going to have to add some more foam tape or something to fill the gap. It is not built real well.I've had Tonneau covers on 2 previous trucks, but this is the first cover that makes noise while drive down the interstate, almost like a low thunder. I've tightened the screw on attachments as tight as they will go, but still noise. None of the covers I've had in the past, vibrate/ripple in the wind as much as this one. I've tried to reseat and I've tried to figure out if wind is getting up under the cover but haven't found any openings. Only thing I can figure is that the fabric is not attached tightly to the frame of the cover. I'm trying to get use to it, but may be in the market for another cover. The price was good, but now I wonder if I should have paid a few dollars more for a better cover.
