The bed liner was my first addition. I don't use the rear seating nearly as often as I use the area for cargo. Besides carrying wood, I often have a few boxes sliding around with axes, machete, chain, 85 ft. of extra rope, snatch block, hitch and d-ring, chainsaw etc. Very much worth the expense for me. I never bothered to screw mine in, just tossed it in and take it out when ever I want.
