I'm interested in converting a combine to a combine with a cupola. Does anyone know of a prototype caboose where the seating in the cupola doesn't have a whole lot underneath it? The cupola on this particular configuration would be between the baggage door and the baggage area. I've seen the maine cabooses where the cupola only has seating on one side, but this is a bit wider; is there a prototype configuration where the seat is suspended from above? That would leave me the aisle width plus the space from the aisle to either wall as an area that large items could ostensibly be moved through.
