Local shop designed, cut, final fit of this project. I still need to remove, sand, spray. I wanted it as shallow as possible (almost too shallow!). Most use will be storage of little used items/tools, parts, etc. as we embark on full-timing in our travel trailer. Provides flat surface to sleep on for the occasions we want to go further into the woods than our glamper will allow. No-fastener design is slick. Truck is Silverado 3500HD 8 foot bed.
