We downsized and then downsized again to a B and for the most part, I am very happy with our choice (but not what we paid for it) I love that we can go just about anyplace, park anywhere and don't have to consider the size. I love that the gas mileage is better than our C or A. I like driving the smaller size better.
What I don't like. Our bed has got to be the worst. Its uncomfortable sleeping and sitting on it. We finally bought a foam top but storing that became and issue. So I'm not comfortable sleeping or sitting.
Surprisingly enough, we have the room and plenty of storage and that isn't an issue.
If I had to do it over I would have kept our Class C
