So, by definition, a Class C seems to include a full size overhead bed in the front over the cab. B+ units can have a pull out bed there, usually under an entertainment center. B units have no bed there.
Many Sprinter rigs are B's, or even B+ unit's.
The class A, B, and C definitions actually have nothing to do with what or where the sleeping arrangements are, but rather with what sort of chassis was used to construct the motorhome.
A class A motorhome is constructed on a bare chassis; Ford or whomever gives the RV maker a frame with wheels, an engine, transmission, etc. but no body work. This is also generally applied when a company makes both the chassis and house parts of a purpose-built RV, though this is a pretty rare situation indeed. The GMC and Bluebird motorhomes are examples that come to mind.
A class C motorhome is constructed on a cutaway chassis (or, very rarely, a cab and chassis). The hood and front doors and driver's compartment come from the chassis maker, and the RV maker adds the house stuff on the back.
A class B motorhome is constructed within a panel van. The outside body is basically as it was produced by the chassis maker (though sometimes the roof is raised), and the RV maker adds the stuff inside.
For reasons that are not entirely clear to me, but I guess because of overall size and shape, bus conversions are generally associated with class A motorhomes even though logically it seems to me they really ought to be categorized as very large class B motorhomes.
A "B+" motorhome is a marketing term, generally applied to a relatively small class C motorhome that usually does not have a bed over the cab. It has no official meaning. Similarly, a "Super C" is also a marketing term, generally applied to larger class C motorhomes that are built on a heavier duty chassis than the van derived chassis used for the majority of class C's.
