The 2551 slide-out could not accommodate a dinette so in 2012 PC extended the coach by 1 foot so both the dinette and the refer would fit..They call it a 2552. ff you wanted a couch they added a narrow pantry with it. We prefer the dinette because of the permanent large table and use the passenger side shirt closet as a pantry..
The factory could change for you for several thousand dollars in one day.
