I was about to say it doesn't exist, but then somebody posted a link at the Allegro 36AU and it does exist! The bunk beds can be easy to find as I've noticed quite a few floor plans that offer them as an option. They put them where a closet would otherwise be. I even saw one that was convertible from bunk beds to a closet by folding the beds up.
What I didn't think you would find a lot of is the bath and a half. You normally only see that in longer units close to the 40 foot range. The reason for it is when they put a nice big bathroom right at the back of the coach. They include the half bath mainly because you can't get to the big back with the slides closed without crawling over the bed. I personally would not get one of those models simply because you lose a lot of square footage to bathrooms and that has to come from someplace else. But some people like their bathrooms, so that's why it is a popular floorplan.
