From the Class B forum topic: In Europe, motorhomes on this chassis are very common (read 70% are on the Fiat Ducato chassis). However, here in the US, the vans and chassis are just starting...
I stand corrected. I meant "C"s. The ACE has one, and several gasser Winnebago "A"s have them.
I didn't see any slide-outs in the pictures of this Winnebago offering. This doesn't mean that there are not any. Assuming the lack of slide-outs, I'm guessing the drop-down beds are a way to allow for more usable space, although for a lot of Americans, it will be something to get used to.
