Just a thought about extra seating when parked. Our 2008 2350 had a swivel passenger seat, when we ordered our 20012 2551 we kept the passenger swivel and added a driver seat swivel. This gave us an extra seat for company and a sense of openness in the cab area.
One drawback is that the factory installed swivel does not accept power seats.
Here is a picture of the cab area with seats swiveled and ready for use.
