Is there any open space above your cabinets ? Our trailer came with some decorative wooden nick-nack "fencing" on the top front edge of several of the cabinets, and most of what we display up there seems to stay pretty much in place, even going down the road. If you have things that would slide, some double sided tape should keep them in place.
