Class B - B+

You're going to get a lot of feedback I suspect. There is no relationship between a B and a B+. Class B's are a modified van and retains the basic shape of a van. A B+ would more accurately be described as a C- but from a marketing perspective nobody sells a minus anything. As you may know the traditional Class C mh has a large section over the cab which can contain a bed, storage, entertainment center. A few years back someone decided to design a Class C that did not have this large area and came up with a more streamlined unit. Then they needed a moniker to delineate this "New" design and came up with B+. But as I tried to describe it is a Class C minus the cab over.

Some manufacturers promote the B+ description. Others such as Winnebago does not. Their streamlined Units are marketed as Class C's. It can be confusing.
