I bought a lockable hard top tonneau for my 15 Tundra. I can take it off in under a minute and it comes with hooks to hang it. The truck is silver so I went with the standard black. Looks great.
I kept my 2004 F150 for farm duty so I won't be taking the cover off for a while
I also decided to just get a fitted rubber bed pad rather than a liner of any type. That has also worked well. Nothing slides around at all.
