Twin bed version of Interstate - Cabinet slides

[wayneskid]

The twin bed Interstate has a handy little section of cabinet at the rear of the curbside bed for storing the shore power cable. This cabinet slides to the Left to allow access to the storage locker under the curbside bed. The problem is that the detents in the two sliding rails are too weak to hold the cabinet in place so it will slide back and forth while underway. These are the same rails used for the drawers and unlike with the drawers, the cabinet section has no latch to hold it in the closed position. The cabinet slides even if the power cable is removed.

Anyone else encounter this problem? Ideas for a fix?
