Older 5th wheels typically will have a bedroom and the sofa will convert into a sleeper.
There are newer models with a two bedroom setup usually in a 36ft long or longer 5th wheel.
Many of the toyhauler 5th wheels have rear beds that lower from the ceiling to create a bedroom in the garage area. These beds also fold into a couch like seat (kind of like a futon does) that allows the area to be used as a living room when not a garage or bedroom.
So the ultimate answer to your question is yes. Keep looking you'll find them.
