ESI ROK Block XL Tailgate Gap Cover 7″ Width and Ultimate Tailgate Seal with Taper Seal 6′ for sidewalls

I was slowly installing this over… months… due to watching all my kids and lack of chunk of time to install, lack of motivation, and no real need to finish it (already did our dusty forest road camping trips this summer, so wasn’t worried until winter salting season). I did the sides earlier and was doing the big gap last. I kept reading instructions and watching a video and then being interrupted. So finally I decided screw it, I’m just laying it down my way and not following all the particulars for my F150 (a bit different layout than the supplied instructions). So it sorta look like crap, but it covers 99% of the gaps. I still have some gap in the corners, and a left over 16” strip of the side bulb strip.I wasn’t sure it adhere to my plastic drop in liner, but after putting the 3M glue down and really pressing it, it seems permanent (I think I was supposed to lay it under the liner to the metal bed). Get the 7” wide one if you have a full size truck or measure properly the gap.It’s a solid product, seems to really stick well and is really thick rubber.My dogs sleep and ride back here and we usually have camp supplies too, plus my camper shell. So really it is to help keep out dust and elements for traveling.I do recommend it.
