Oh, and when doing an interior in liner, I also say stop at the end before you get to the tailgate opening. Even as loose as we think the fitment is on panels and such, the thickness of a liner will mess you up when it comes to adjusting the tailgate properly.
Best to leave it just short of the lip.
I know that's not what this thread is about, but since we're talking about using bedliners, figured I'd throw it out there anyway.
