Back in the day, Class A motorhomes were mainly designed for couples. Most floor plans had a bedroom with a king or queen size bed. Most had couches and dinettes that made into beds, but the design for was for couples. Class C's often came with bunks and the over cab beds and were more designed for families. More modern Class A makers do seem to be making "family" models with bunk beds and other features. My favorite is a design that has fold down bunk beds in a side room, and when you fold the beds up the entire room becomes a closet. Best of both worlds.
