Interested in the comments that the front cab of a C is useless while stopped. Probably depends on the floor plan. We are two adults plus large dog, and have a small C Sprinter - Itasca Navion iQ (model has no overhead bunk) 24G (rear queen bed slide out.)
One thing I like a lot about it is that both the comfortable cab seats swivel very smoothly and easily to face the living room in about 10 seconds. Directly above are a skylight (in lieu of the bunk) and a powered vent with screen or shade.
So the living area (sofa slide) is roomy, seats four, and has natural light. Cab space is definitely not wasted. The TV on the wall over a kitchen counter swivels at an angle so it's visible from the sofa or chairs - no twisting of the neck to view, wherever you are sitting.
