I added an extra roller catch to each cabinet in the rear of the rig which seems to have helped 90% of the time.
Another thing I have learned is to open the slide enough to squeeze by the island, and walk to the back to visually check things. Sometimes things on the floor get behind the trim on the slides while traveling. I've never lost a cabinet door yet, but I have bent the trim, so that's my solution to the problem.
