Recently, I had a Line-X liner installed. The liner is great and the guys did an absolutely perfect job. Today, I noticed one of the covers in the bed where the LED bed lights would be (my truck did not come with them) had fallen out. Thankfully, it was still in the bed. I looked at the other one and it was almost out also. Not a big deal, a little gorilla glue and it should be good. I am wondering if anyone else that has had a liner installed could share if they have had this issue? There was no damage to the covers, it just seems that since the liner has added just a tiny bit of thickness, the tabs are not grabbing and holding the cover in.
