This isn't a bad floorplan, but on the class B forum, it does have some shortcomings (and they are subjective... something that doesn't bother me may be a deal-breaker for others, especially the fact that the bed may be too narrow for a couple.)
I would guess that this is Winnebago's first stab on this chassis. I'm hoping they would come out with a floor plan more like a PW Ascent or a RT SS Agile eventually, even if they do a floorplan similar to some European rigs which use multi-section sliding doors (like the Travato's bathroom door), but have the shower be in the aisle. That way, the bathroom wouldn't take up as much space as it does in the Travato, but yet, with a closed door, it would be big enough to be usable and private.
Maybe they could get Truma (a German company named after Truman) to sell their products in the US. They have a 14 liter water heater (1500 watts propane, 850 on electric) that would be very compact and usable for this type of rig. To boot, when the temperature gets near 35 degrees, the water heater will dump its contents, so it doesn't freeze.
