We have plenty of storage in the B for the things we take. We just take less stuff, no duplicates, and always seek multipurpose stuff.
I actually find the bed more comfortable than the airmattress (sorry, "sleep number") that was in the A. It's actually a bit wider.
You do have to get used to squeezing past each other on the way to the bathroom, kitchen, door, etc.
I like the fact that setup and breakdown is MUCH easier in the B. And no doubt, traveling on the road is a lot more relaxing.
That said, it of course depends on your needs. The A was nice. We just don't need it now.
