In our campervan, tradition dictates that the trash is kept in the cabinet under the sink. Our variation is that we use a small Rubbermaid container with a plastic bag liner for a very compact version. Probably about an 8" high, 5" wide, 10" deep container. Fits on a shelf right below the sink, behind the cabinet door....The obvious answer is a pull out trash can under the sink. We can do better than that!![]()
