In our class B, the enclosed toilet structure was eliminated, and we have a cassette toilet in a flex space area that can be storage or an additional sleeping area. The cassette toilet is available, but we have yet to use it. We can carry loads of gear, even dirt bikes, or a full target practice set-up. Our beds fold into a working table suitable for Gunsmithing a long gun. As I said in a previous post, lots of flexibility in the design of Sprinter vans.
