I switched all my locks to RV Locks. Keyless on the door, and replacement slam matches on most other hatches. The front and two propane door I used cam locks. I reversed what you want, I put a lock on each side and a twist lock in the center. This way when Iím around I leave the locks unlocked and just twist the center to keep it shut. When I leave I lock the two sides.
