I have a 2004 tacoma prerunner double cab. i am thinking about getting a bed extender. how easy are they to install? I am also worried about it getting stolen. Does it just come off the truck by had when you dont want to use? Or is it locked down to prevent theft? I also have a linex bed liner already in the bed. thank you.

you use the 4 Phillps screws by the back tail gate / 20 min. install/ to prevent theft I would get a pop lock for the tail gate
