The one I saw today was a Thor Chateau Bunk house model. You are right, it has the over the cab bed, the dinette folds down to make a bed, the couch folds out or some sort of thing for a bed and then the big bed in the back. PLUS, it has two single bunks, one on top and one on bottom; just south of the kitchen. Between the fridge and the bedroom. The dinette, kitchen, bunks, and bedroom closets are all on one big slide that looks like it goes from one end to the other. When the slide is pulled in, you have to go through the bathroom to get to the bedroom. The step up is between the fridge and the bathroom door.
I am pretty sure this was not a super C, it has the regular Ford van front end, with a V-10 gasser.
