My truck came stock with a bed liner....well it looks like at the very end by the tailgate it is puckering up. So much so that i can look up underneath there and it looks rubbed BAD.

I have no idea if this is normal....

 

yank it out and get a sprayed on liner.

 

It's normal for a drop in liner. Get LineX sprayed in there, you won't regret it.

 

possibility....

With the drop in bed liners is there always rubbing?

 

I'd say yes. If I'm not mistaken they are only held in by the 4 tie down hooks and with the changing temperatures the plastic will expand and contract. Short of attaching the drop in liners with screws or an adhesive, there is no way to stop it from rubbing the sheet metal.

 

Go with a REFLEX Spray liner, I had LINE-X in my old truck and it was good but I like the REFLEX better feels more solid, and hasn't peeled my line-x peeled after about 4 months

 

If your LineX peeled it wasn't because of a defective product, the dealer didn't prep the box properly.
