Huh! Drop down bed.. that's sure different. Might be a little to claustrophobic for those sleeping under it..
I have no idea what the price range of that unit is, but I would want to compare it to the Itasca Navion c class first.
We rented a Navion equipped with the Mercedes Turbo diesel, for a trip down to Cailfornia, and fell in love with it. It was extremely kind on fuel consumption, very comfortable to ride in, and handled like a dream at all speeds. The slide out, and cab over bed offered great sleeping accommodation and lots of cabin space. Everything about it, other than perhaps the smaller stove top, was fantastic. 
I would buy one in a heartbeat, if I could only afford it..lol
