Made up a shelf for the cab area. The lack of anywhere to rest small items during the motoring was crazy. The hard to reach tray and cup holders are still accessible. Held in with 3 screws, so easy to remove. Shelf liner glued and clear caulked to the shelf. Level and Solid.
Thanks! A few 9 degree angles made the unit fit nice and snug with the “cup holder” unit below. Tan shelf liner, glued and caulked, made the shelf hold items without sliding.
