Was looking for Class C but now looking for Class B information
The suggestion above to purchase a much older depreciated rig to find what you truly like based on floor plan is a good idea.
On the B+ difference, I suggest that there are a few added differences than just the absence of the bunk, depending on model. Ours for example is quite a bit narrower in width than a C, but about 18 inches wider than a typical B. The bunk being gone eliminates (or at least reduces) the risk of water intrusion that is so common on C bunks - several examples of this problem are on this site; I walked away from several Cs when we looked for and had one. In our case the front of the rig is molded into the one piece roof with no seam to leak. Wind noise is also reduced and the field of view is improved. All that said, the C is still a great choice for many people and you can't beat a traditional B for maneuvering and parking. We find that we use our rig far more often even for day trips due to its size, but that was also part of our express purpose as our blog shows.
