Installed a new cargo area floor so that I could mount up an ARB fridge slide. The floor replaces an all-weather mat and OEM storage cubby cover. I also removed the OEM sub as it's placement always bothered me. I honestly can't tell the difference with it gone.
I made it from 1/2" birch plywood with 11/16" supports/spacers to even everything out underneath. Added a small hinged door on the right side so I can access stuff in the storage cubby. Everything is attached with stainless hardware to the OEM d-ring locations. Rattle canned black, matte clear-coated, then covered top with outdoor carpet from Home Depot. It's a really good match for the OEM carpet. I kept a few inches open to the left of the slider so I can store a 100W solar suitcase upright while on the move.
