On my Scamp
13, I pulled the flatware drawer out, drilled two holes through the bottom near the back, put drawer back in and dropped two bolts thru the holes. Now the drawer pulls almost all the way out, stops and droops little in front (if I want to remove the drawer, I just lift the bolts).
I found (at Target, I think) a plastic cutting board that is exactly the right size to insert at the back of the drawer between the fiberglass cabinet and the drawer sides, with the front edge resting on the drawer front; it is level because of the droopy drawers (no relation to Charles' Drawers).
The back edge of a wooden cutting board could be rabbeted or extended to accomplish the same thing (extension could be sized for the slot, allowing a larger board if preferred). When not in use my board is stowed nearby against the forward edge of the cabinet, on edge on the bottom bunk.
I prefer the drawer-top to a sink-mounted or stove-mounted cutting board, because it's not in my way when I don't need it, I can cook'n cut simultaneously, it provides extra counter space, and I keep a container full of sink stuf in the sink when traveling (stuf is contained in the sink from jumping around), YMMV.
Drawback is if I need to withdraw the board to get something out of the drawer, but I keep my cutting knives in a block secured to the counter top aft of the faucet, so that is very seldom.
