OK, something different here: I went with a BedRug in an F-150 pulling my TT.
I actually considered Line-X and Rhino, but I'm meticulous about my vehicles and rarely use the bed for dirty things, so it worked very well for me.
It is the consistency of really thick trunk carpet and mounts with velcro adhesive strips. I never removed it but you could easily. I did carry a few loads of mulch and just pressure washed it out. It was still like new after 4 years (under a tonneau cover). I think it was about $400.
The biggest downside, I always felt like a dork vacuuming my truck bed
.
It's not for everyone but it was perfect for me.
