I found another use for the "never used" cutting board. I routed it out to hold a silverware tray. I removed the hinges and attached the front to the cutting board and it now is the silverware drawer. Outside of getting the alignment right the hardest part was finding the latch that matched the other drawers. I used 2 screws in the back for stops so the drawer won't be pulled out too far.
A fellow RVer found a small ironing board and attached a board to it the fits the slot for the cutting board. It works pretty slick and can be stored under the seat of the dinette if you have one. The brace on the bottom of the seat holds the board pretty well.
