Would you ever consider a small class C?

I would add that my boss has a Sprinter that he personally customized into a B. His Sprinter and my Clipper are the same length, his Sprinter is taller, my Clipper is wider. For that little difference in size dimensions, the Clipper's layout works much better for me than his Sprinter would - but the Clipper would have never worked for him. He does get better mileage by far, but I have the ability to take in an overnight guest and have moving room with the dogs.

So, I think folks should consider both and work out the pros and cons for how they intend on using it - then make the decision that's right for them.
